ACCESSORIES & OPTIONS

Battery Packs and Cases

The following rechargeable Ni-Cd battery packs are recommended for
u: with the FT-470:
note,(see battery list above)

In some countries, one or more of the above may be supplied with the
transceiver. If not, contact your Yaesu dealer to purchase the desired
battery pack or case. We do not recommend use of any other type of
battery with the FT-470: using another type may affect your warranty.

The FNB-9 through FNB-12, FNB-14 and FNB-17 may be recharged
either while attached to the transceiver or separately, using the battery
chargers described on the following pages. Each Ni-Cd pack should be
fully charged before it is used with the transceiver for the first time.
Note that each of these packs requires a different wall charger:
NC-27B/C for the FNB-9, NC-28B/C for the FNB-10/-17, NC-IgB/C for
FNB-11 or FNB-12, and NC-34B/C for FNB-14. Make certain that you
use the correct charger for each pack. The NC-29 Desktop Quic.k
Charger may be used with all of these Ni-Cd packs.

- 8

RF power output from the transmitter will differ in some cases according
to which type of battery is used, as shown in the RF Power Chart
in the Specifications section.

Battery Removal and Replacement
1.
Make sure that the VOL control is set into the OFF click-stop, and
remove the protective soft or hard case, if used.

2.
Grasp the upper portion of the transceiver with your left hand, so
that your palm is over the speaker and your left thumb is on the
UNLOCK button.

3.
Move the UNLOCK button in the direction indicated by the small
arrowhead, while using your right hand to slide the battery case
toward the side with the UNLOCK button. The battery case should
slide smoothly out of its track.

4.
To open the FBA-9, FBA-10 or FBA-17 battery case, place both of
your thumbs on the mounting tracks on top of the case and gently pry
the tracks apart. Install six batteries, paying attention to the polarity
indicated inside the case. Always replace all six cells.
Do not attempt to open any of the rechargeable Ni-Cd packs.

5.
To replace the battery case or Ni-Cd pack, repeat steps 2 and 3
above, simply sliding the battery case in the other direction after
aligning the shorter side of the battery case with the track below the
UNLOCK button.

.
Battery Chargers

It is not necessary to remove the battery pack from the transceiver whe
charging, but transceiver operation may be impaired (by noise) whil.
charging the battery. Therefore we recommend having an extra battery
pack on hand so that the transceiver can be used while the spare pack
is being charged.
Do not attempt to recharge dry cell batteries used in the FBA-9
FBA-10 or FBA-17.

NC-18B/C
The NC-18B (ll7VAC) and NColSC (220-234VAC) are compacl
chargers for recharging the FNB-11 and FNB-12 Ni-Cd battery packs
from the AC line. A completely discharged pack requires approximately
15 hours to recharge with the NC-18B/C. Do not attempt to charge any
of the other Ni-Cd packs with the NC-18B/C, as the charging voltage
is too high to safely charge those packs.

NC-27B]C
The NC-27B (I17VAC) and NC-27C (220-234VAC) are compact chargers for
recharging the FNB-9 Ni-Cd battery pack from the AC line.
A completely discharged pack requires approximately 15 hours to recharge
with the NC-27B/C. Do not attempt to charge any of the other
Ni-Cd packs with the NC-27B/C, as the charging voltage is not high
enough.

NC-28B/C
The NC-28B (ll7VAC) and NC-28C (220-234VAC) are compact
chargers for recharging the FNB-10 and FNB-17 Ni-Cd battery packs
from the AC line. A completely discharged pack requires approximately
15 hours to recharge with the NC-28B/C. Do not attempt to charge any of the
other Ni-Cd packs with the NC-28B/C, as the charging voltage is not correct
for those packs.

- 10 --

NC-34B/C
The NC-34B (ll7VAC) and NC-34C (220-234VAC) are compact
chargers for recharging the FNB-14 Ni-Cd battery pack from the AC
line. A completely discharged pack requires approximately 15 hours to
recharge with the NC-34B/C. Do not attempt to charge any of the other
Ni-Cd packs with the NC-34B/C, as the charging voltage and current
are not correct for those packs.

NC-29 5-hour Quick Charger
The NC-29 is a universal .battery charger with quick and trickle charging
modes for all of the FNB Ni-Cd packs listed on page 8. The quick
mode is automatically selected initially, to bring the battery pack up to
full charge as fast as safely possible using an internal timer. Three LED
indicators show elapsed charging time after 1, 3 and 5 hours. The charger
then automatically reverts to the trickle mode (green LED indicator),
to prevent self-discharge. The quick mode recharges a completely discharged
battery in about 5 hours, depending on temperature.

CAUTION: When using the NC-29, do not remove and then replace a
battery from the charger while it is charging, as this will reset the timer
and may then overcharge the battery.

PA-6 Mobile DC-DC Adapter/Charger for FNB-9, FNB-10, FNB-14 and
FNB-17
The PA-6 is a DC-DC adapter for use when operating the transceiver
mobile, and for charging the FNB-9, FNB-10, FNB-14 and FNB-17
Ni-Cd battery packs. The PA-6 recharges a completely discharged
FNB-9 in about 5 hours, an FNB-10/-17 in about 15 hours, or trickle
charges an FNB-14 (to full charge in about 35 hours). Ca."e must be used
to avoid overcharging the batteries, as the PA-6 does not include a
timer. The PA-6 cannot be used for charging the FNB-11 or FNB-12, as
the charging voltage is too low.
Use with 12-volt negative ground electrical systems only.

.
Speaker/Microphones
The MH- 12A2B and MHr 18A2 B Speaker/Mics and MH- 19A2B Earpiece
/Mic can be used to increase operating convenience and extend communications
range and signal strength. Each is equipped with a dual plug connector which
mates with the EAR and MIC jacks on the top panel of
the transceiver, disabling the internal speaker and microphone. The cable
allows the transceiver to be left clipped to your belt, or to be held
overhead above obstructions for improved performance, if required. For
mobile operation with the MMB-32A Mobile Hanger, the transceiver can
be left in the Hanger during operation.

A Speaker/Mic can be held close to your ear during reception; or an
external earphone can be connected to the transceiver via the Speaker/Mic
plug, attenuating audio from the speaker in the Speaker/Mic. To
transmit just hold the Speaker/Mic close to your mouth and close the
PTT switch on the microphone (or on the cord of the MH-19A2B).

Antenna Considerations
While the supplied YHA-28 rubber flex antenna is convenient for
short-range operation, the standard BNC connector allows use of higher
gain antennas for extended range base or mobile operation. However,
any antenna used with the FT-470 must have an impedance close to 50
ohms on the operating frequency(ies). Therefore, for dual band operation,
you have two options:

(a) Use an antenna specifically designed for 2m/70cm operation.
(b) Use two single band antennas, connected through an antenna
duplexer (such as the Yaesu model AD-2) to the transceiver.

Also, if the antenna is connected with a feedline, use only good quality
50-ohm coaxial cable to avoid losses. To obtain a proper fit with some
BNC plugs, you may need to remove the rubber gasket around the
antenna jack on the transceiver.

OPERATION
This chapter describes the various transceiver functions in detail. After
studying these descriptions, keep the FT-470 Operator's Quick Reference
Card handy in case you need to refresh your memory.

Preliminary Operating Information
Before operating the transceiver for the first time, charge the battery
pack completely (if using Ni-Cd batteries) as described on pages 8
through 11. If using a dry cell battery case, install the batteries as
described
on page 9.

Connect the YHA-28 rubber flex antenna to the antenna jack on the top
panel. Never operate the transceiver without an antenna connected.

For now, do not connect a Speaker/Mic (until you are familiar with basic
operation).

Before proceeding, please read the Controls and Connectors chapter if
you have not already, to familiarize yourself with the functions of the
controls. Note especially item (7) on page 7, which describes the
terminology used in this chapter when referring to the keys.

Except for special cases mentioned later, the lower 16 keys serve as a
DTMF (Dual Tone Multi Frequency) tone generator during transmission.

If you have trouble getting the transceiver to work as described, see "In
Case of Problems" on page 31.

Squelch Setup
Set the SQL control fully counterclockwise, rotate the VOL control out
of the click-stop and adjust for a comfortable volume on the noise or
received signal: The BUSY/TX indicator LED should glow green. If a signal is
present, rotate the DIAL selector on the top panel to a channel
where only noise is heard.

-- 13

Adjust the SQL control just to the point where the noise is silenced and the
LED is extinguished. If the SQL control is set further clockwise, sensitivity
to weak signals will be reduced. Now, whenever a signal
reaches the receiver that is strong enough to open the squelch, the indicator
will glow green.

Note that while receiving,, one or more bargraph segments may appear
along the bottom of the display, indicating signal strength on the
receiving frequency. This indication is not affected by the squelch
setting, so even squelched signals may have some indication. If you
notice more than one or two bargraph segments appearing while the
squelch is still closed,, try reducing the squelch control setting (if you
want to hear weak signal).

The Monitor switch on the A & H versions (just above the PTT switch)
allows checking for channel activity beneath the squelch level and to
adjust the volume without having to adjust the squelch: just press the
Monitor witch and the squelch will open. Above the Monitor switch (the
Burst switch on European versions) is the Lamp switch. Press it to light
the display and keypad.

Important Keypad Information
If the keypad beeper is enabled, each key on the keypad produces its
own beep (or combination) when the key action is accepted. If you don't
hear a beep when a key is pressed, either the volume is set too low, or
the keystrbke was not accepted. Durirg transmission, key tones of the
lower 16 keys are the DTMF tone pairs (which are also transmittedl.

Pressing the F/M key (at the lower right corner) momentarily activates
the alternate keypad functions, labelled on the panel ]ust above each
key. Note, (See key pad discription at the beginning)
If no key is pressed within three seconds of pressing the F/M key, the keys
return to their standard functions, labelled on each keyface.
Throughout this manual, when we say "press the F/M key" we mean
press it just momentarily (less than -second), unless specified otherwise.

The keypad can be locked to prevent inadvertent changes in frequency
and functions, by pressing F/M followed by the LOCK(6) key.

- 14
When the.
keypad is locked a small "I" in reversed letters is displayed in the lower
left corner, and the keypad tones (while receiving) are then as follows:

Feel free to use the keypad as a piano when the keypad is locked (who
said we would couldn't fit a piano in a hand-held?). The only key
combination that will affect transceiver operation is F/M followed by
LOCK(6) within three seconds, which unlocks the locked keypad.
When unlocked, the tones produced by the arrow keys are changed to
audibly indicate the direction of the arrow, and some other keys also
sound twice in certain conditions.

You can expect keypad operation to become easier as you become accustomed to
the tone(s) associated with each key and function. If you want to disable the
keypad beeper, press F/M and then the BEEP(8) key.
Repeat these keystrokes to turn it back on (we recommend you keep it
on at least while learning the key functions).

The PTT switch can also be locked (independently of the keypad) to prevent
inadvertent transmission, by pressing F/M followed by the PTT LOCK(9) key.
When the PTT is locked a small "Ptt" in reverse letters is
displayed in the lower left corner. Press the same keys again to unlock.

Band Selection
Press the BAND key on the top row to switch the primary operating band
between 2m and 70cm bands.

VFO Frequency & Step Selection
Make sure the :keypad is unlocked, and press the VFO button, if necessary,
to select the VFO mode. The FT-470 has two
vfos, labelled A and B, either of which can be used for all of the procedures
described in this manual. You can change vfos with the VFO button at any
time, allowing one to serve as an extra memory.

You have several ways to tune the FT-470: in selectable steps or 1 MHz
steps with the arrow keys or DIAL knob, and direct keypad entry.
Use the DIAL knob to tune the displayed VFO frequency at the current
channel step rate. You can also press the arrow keys momentarily to do this,
but if you press an arrow key for more than -second scanning will start. This
is described later, so for now, just press an arrow key again
to stop (if you have to).

To change the MHz range of the VFO, you can press the F/M key
followed by an arrow key (or turn the DIAL knob). Note the beeps when
using the arrow keys: (-) when moving up, and () when moving down. When done
press F/M again, or just wait three seconds.

You can also enter a frequency directly just by keying in the 1 MHz
and the kHz digits. If you are using 5 or 10 kHz steps enter four digits.
Otherwise just three digits will do. Partial entries can be cancelled with
the VFO key.

Tuning steps are factory preset according to version. To change to
another step size press F/M and then STEP(7) and use the DIAL knob or
arrow keys to select 5, 10, 12.5, 20 or 25 kHz steps (displayed at the
right, the "5" or "P" in the shaded box at the upper left is the scan mode
indicator, described later}. Once the desired step is displayed, press
STEP(7) by itself to return to the VFO frequency display.

-- 16 --

Dual Band Reception
The SUB key along the top row allows you to control the secondary band.
During the above band and frequency selection procedures, you may have seen
the secondary band frequency displayed, or you may have
seen only "---" (in the right half of the display). By pressing the SUB key
you can choose to either display (and receive on) the secondary band, or to
hide it and operate the FT-470 like a single band transceiver.
When the secondary band is displayed the receiver combines the
received audio from both displayed frequencies, so you can listen for a
call on one band while monitoring or working stations on the other. Use
the Balance control to adjust the relative audio levels of the two bands, if
necessary, after the VOLume control has been set.
Changes to the frequency or other settings can only be made on the
primary band (displayed at the left). So if you want to change settings
of the secondary band you must temporarily make it the primary band
by pressing the BAND key. Then make the desired changes, and press
BAND again to return it to secondary status. Note: tone squelch/pager
features are only effective on the primary band, regardless of settings.

Transmitting
Press F/M and then LOW(3) to toggle between high and low power
output. The pitch of the keypad beeper will indicate whether high or
low power is being selected, and "LOW" is displayed above the 1 MHz digit of
the primary frequency when low power is selected
(we recommend using low power whenever possible to minimize possible
interference to other stations and prolong battery life).

When you wish to transmit, wait until the channel is clear (BUSY/TX lamp
off), and squeeze the PTT switch. During transmission the BUSY]TX lamp glows
red or orange (if the secondary channel is busy), and
relative power output is indicated graphically along the bottom of the
display. Release the PTT switch to receive.

-- 17

If using a European version, press the BURST switch (above the PTT
switch) to transmit a 1750 Hz tone to access repeaters that require it.

Repeater Offsets
The ARS (Automatic Repeater Shift) feature provides repeater offset of
the transmit frequency whenever you are tuned to a standard repeater
subband When enabled, a small "-" or "+" displayed
above the 100s of MHz digit of the secondary frequency indicates that
repeater shift is active, and closing the push-to-talk switch changes the
display to the (offset) transmit frequency.
The ARS function is disabled at the factory. It is toggled on and off by
pressing F/M, RPT, F/M and RPT (that is, each key, twice alternately).
Pressing F/M and RPT the first time displays the repeater offset
(adjustable) at the right, and if ARS is now enabled, an "A" in the
shaded box at the upper left. With this display, pressing only the F/M
key toggles ARS between enabled and disabled states, and RPT returns
the display to the operating frequency. So after pressing F/M and RPT
the first time, if you want to leave ARS as it is, just press RPT.
Otherwise, press F/M to change it and press RPT once more when done.

When the ARS feature is inactive (either disabled, or when tuned outside of
the standard repeater subbands) the RPT key manually activates
transmitter offset from the displayed receiving frequency for plus or
minus shift. Just press RPT: once for minus shift, or twice for plus shift
("-" or "+" disllayed above the 100 MHz secondary frequency digit).
When you press the PTT switch to transmit (or the REV key along the
top row to reverse transmit and receive frequencies), the display will shift
down or up by the offset programmed for that band, if in band (or else 'Err'
is displayed). Pressing RPT again returns you to simplex
operation.

Changing the Standard Repeater Offset
As mentioned above, a default repeater offset is programmed in the
transceiver for each band, and can be easily reprogrammed as desired.
If you have one or two repeaters in your area with non-standard splits,
you can program separate transmit and receive frequencies in memory
as described later. However, if most or all of the repeaters you use have
an offset different than the default, you can reprogram the standard
offset (as used by the RPT key and ARS) instead.

To change the repeater offset press F/M and the RPT key to display the
currently programmed offset. Then use the DIAL knob, arrow keys or
numeric keypad entry to change the display.ed offset as required. Any
repeater offset entry must be a multiple of 50 kHz. If you use the keypad
to enter the new offset you will start with the 10Ws of MHz digit, so if
the new offset is less than 1 MHz, you will have to enter two 0s, followed
by the 100Ws of kHz and 10s of kHz digits. For example, press
0090 to select 900 kHz offset (the lVs of kHz digit is assumed to be
always zero). After selecting the desired offset press RPT to return to
the VFO frequency display (but make sure the ARS feature is set as
desired ("A" in the shaded box at the upper le't if enabled).

Memory Storage
The FT-470 has 42 memories: for each band there are eighteen general
purpose memories, numbered 1 through 18, and three special memories,
labelled C, L and U. All of these memories can store separate receive
and transmit frequencies or repeater offset, and tone squelch data. The
C memory is recalled instantly when the CALL key at the left end of the top
row of the keypad is pressed (for use as an emergency or call channel), and
the L and U memories are used for PMS operation,
described later

- 19

To store a frequency in memory:
(1)
select the desired frequency (and repeater offset, if desired) in
the VFO mode as described above.
2 Press and hold the F/M key for -second (until the second beep
sounds). A Memory number appears blinking in the shaded box
at the upper left corner of the display.

(3)Within five seconds of step (2), use the DIAL knob or arrow keys
to select the desired Memory for storage. If you select one that
was already being used, it will be overwritten with new data in
the next step.

(4) Press F/M again to store the displayed data into the selected
Memory: the Memory number will stop blinking for a second,
and then disappear as operation continues in the VFO mode.

When storing split-frequency memories you have the choice of either the
Repeater Offset method, described previously, or of storing independent
transmit and receive frequencies. For independent transmit and
receive frequencies, just store the receive frequency as described above,
and then tune to the desired transmit frequency, press F/M again for -
second, and then press and hold the PTT switch while pressing F/M once
more (the transmitter is not activated in this case). By either method the
results will be the same in operation, except that storing an independent
transmit frequency applies only to one memory, while the offset method
applies to all (when the RPT button is pressed).

Memory Recall & Copy
There are two ways to recall stored memories. If you know the memory
number, just enter it on the keypad and then press MR (the "I" memory
is 19 for this purpose, while the "U" memory is 20). If you aren't sure of
the memory number, press the MR to select the Memory mode (a Memory
number/letter is displayed at the upper left), and then use the DIAL
knob or arrow keys to select the desired memory. Naturally, vacant
memories are not displayed.

- 20

For split-frequency memories, "minus" or "+" will be displayed to remind
you of the shift if stored by the offset method. If you stored a memory
with a separate transmit frequency, both are displayed together. In
either case, you can press the REV key to check the transmit frequency
without transmitting (and press it again to return).
You can retune a selected memory by pressing the MR key: a small "MT" appears
under the channel box at the upper left, and you can tune the displayed
memory frequency in the same ways as described for the vfo3. If you want to
store the new memory settings in the current, or another memory, just follow
steps (2) - (4) of the memory storage
procedure above: operation will be left on the memory.
If you want to copy memory data to a vfo overwriting previous data),
you can do so while the memory retune feature is active: just press F/M
.and the VFO key to copy to the last-used VFO. If you dont want to save
your changes to the memory, press only the MR key to return to the
original memory data.

Hiding and Erasing Memories
As already mentioned, storing data in a memory automatically overwrites data
that was previously stored there. However, if you regularly move from one
area to another, you may not want to use the same memories
all the time, or you may wish to change your operating memories without
having to rewrite them from scratch. This can be done by masking
certain memories so that they are completely hidden from operation, and
recalling them only when desired for operation.

To completely mask a memory, recall it and press the F/M key for
-second (until the memory number blinks). Then press the MR key. This
causes the display to change to memory 1, and the previously-selected
memory is no longer selectable manually, or by scanning (as described
later). Note that you cannot hide memory 1.

To unmask a hidden memory for use, recall any memory and press F/M
for second. Then select the memory to be restored, and press MR.

When you have hidden memories, avoid accidentally overwriting them.

Call Channel Memory
The call channel memory can be instantly recalled by pressing the CALL
key on the top row of the keypad. "C" appears in the memory window at
the upper left corner of the display.
As mentioned earlier, you can store the same kinds of data in the CALL
channel as in the general purpose memories: just follow steps (1) and (2) of
the memory storage procedure, and then press the CALL key. Also,
if storing a separate transmit frequency, press the CALL key while holding
the PTT switch when storing the transmit frequency (after saving the receive
frequency - the transceiver stays in the VFO mode).

Alternating Band Memory Selection
If you want to select among memories on both bands, press F/M and then
ALT(BAND) to activate Alternating Band Memory Selection. "ALT" is displayed
above the MHz of the secondary frequency display, and memory selection will
alternately select memories on each band,
This feature can be especially convenient for memory scanning both
bands, described later.
To cancel Alternating Band Memory Selection press the BAND, MR,
VFO or CALL key (depending on where you want operation to commence).

.
Scanning
Before starting the scanner, make sure background noise is squelched on
a clear channel. Scanning is started and stopped by the arrow keys. Just
press and hold either key for more than 1 second to start the scanner.
If in the VFO mode (or on the CALL channel), the whole band will be scanned.
If in the memory mode, only the memories will be scanned (on alternate bands
if the ALT feature is active).
The scanner pauses (and the decimal blinks) when a signal is detected which
is strong enough to open the squelch. You have a choice of two scan-resume
modes: either Pause mode, in which the scanner pauses for
as long as the carrier keeps the squelch open, or the 5-second duration mode,
in which the scanner pauses for five seconds and then resumes scanning
whether or not the signal is still present.

To set the scan-resume mode, press F/M and then STEP(7). A small "P"
or "5" in the shaded box at the upper left indicates the current mode.
Press F/M to change it, or just press STEP(7) alone to return to the
frequency display.

You can stop the scanner manually by pressing the PTT or an arrow key, or by
turning the DIAL knob.

The FT-470 can scan the secondary band while operating or also
scanning on the primary band. However, you cannot manually stop the
scanner on the secondary band (without first pressing BAND to change it to
the primary band).
NOTE: The scanner checks about 14 channels per second. To prevent
interruption by the power saver, saver operation is automatically
suspended during scanning, resulting in some increase in power drain.

Memory Skip Scanning
When you have some busy channels stored in memories you may wish to
skip them when scanning other memories, but still have them available
for manual selection. You can mark a memory to be skipped by pressingS.
F]M and then SKIP(MR) while the memory is recalled. A tiny arrowhead will
appear just to the right of the memory number box, and this memory
will be skipped during scanning (you can still recall it manually).

To unmask a scan-skip memory, just repeat the same steps you took to
mask it: select the memory manually, and press F/M and SKIP(MR).

Programmable Memory Scanning (PMS)
In addition to band and memory scanning, the FT-470 can scan between
two frequencies stored in the special memories "L" and "U":

(1)
Store the lower edge of the desired scanning range in memory L, and the
upper edge in memory U.
(2)
With either memory U or L recalled, press the MR key. "MT"
appears under the memory number box at the upper left.
You can now tune or scan as described previously, between the nearest
multiples of 100 kHz (xxx.000, xxx.100, xxx.200, etc.) below memories
L and U.
To cancel PMS operation, stop scanning, if necessary (DIAL knob, arrow
keys or PTT), and press the MR key to return to regular memory
operation, or the VFO key to return to VFO mode.

Priority Channel Monitoring
Priority monitoring allows automatic checking for activity on a memory
every five seconds while operating on a vfo or other memories. When a
signal appears on the priority memory while receiving, operation will
automatically shift to that memory, for as long as a carrier is received.
If you transmit while paused on the priority memory, priority monitoring
is cancelled and operation stays on the priority memory.

The squelch must first be preset, and the frequency to be monitored must
be stored in a memory (this MUST be memory 1 if you will be operating
on other memories during priority monitoring).

Press the VFO key to operate on a vfo, or else select the memory you
want to operate on, and then press F/M and PRI{VFO}. A 'P' will appear
in the memory window at the upper left corner of the display, and about
every five seconds the displayed frequency will shift to the priority
memory briefly while the receiver checks for a signal.
As long as no signal appears on the priority memory to open the squelch,
you can tune, scan, transmit and receive on the vfo, or select and
operate on other memories or even on the other band. If a station you
wish to talk with appears on the priority memory, press the PTT switch
momentarily while receiving his signal, to stop priority checking (if you
have switched bands, you will have to return to the band on which the
signal has appeared, by pressing the BAND key first. Otherwise, if you
don't transmit when a signal appears on the priority memory, checking
will pause and the decimal on the display will blink; then priority
monitoring will resume (according to how you set the scan resume mode -
either after a 5-second pause, or after the carrier drops). To cancel
priority monitoring manually, press either the MR or VFO key.
Note that you can use any other memory as a priority channel in the
above procedure when you will be operating on a vfo (while monitoring).

Tone Squelch/Pager Operation
The FT-470 can be used to silently monitor for calls on busy channels
and to transmit CTCSS tones. The transmit (encode) function superimposes
a subaudible tone (at a frequency too low to be heard) on the
transmitted carrier, while the decode function monitors receiver audio
through a narrow filter at the same subaudible frequency, keeping the
squelch closed until a matching tone is received. If the paging bell
feature is activated, an incoming signal with the matching tone will
cause the speaker to sound an alerting "ring", and a small bell icon will
blink above the 10's of MHz digit of the primary frequency display (so
that you know if a call came in while you were busy elsewhere).
To check or set the CTCSS tone frequency, press F/M and then
TSET(2). The tone frequency will be displayed (in Hz). To change the
tone frequency, rotate the DIAL knob or press the arrow keys until the
display shows the tone frequency you require, then press TSET(2) again to
return to the operating frequency.
NOTE: the keypad beeper it MUST be activated if the paging ring is to
sound when a CTCSS call is received. Press F/M and then BEEP(8) to
toggle the keypad/ring tones on, if desired.
With the keypad/ring tones turned on, you must also activate the paging
bell if you want to use this feature. Press F/M and then BELL(0): a small
bell icon appears above the 10is of kHz digit of the primary frequency
when activated. This icon will blink after a call is received.
To activate tone squelch press F/M and then the TONE(1) key. A "T"
will appear at the top center of the display, and the tone generator will
be enabled for transmission. Press F/M and TONE(I) again and "SQ"
will be displayed next to the "T" as tone squelch is enabled for both
transmission and reception (only a matching tone will open the squelch).
Press F/M and TONE(l) once more to turn off the tone squelch features.
Once you have the tone squelch set up the way you want, you can store it in
any memory. Afterwards, to change stored settings, just recall the memory,
reset the tone frequency or function, and store the memory
again (press and hold F/M second, and then again momentarily).

Power Saver
The Power Saver allows the transceiver to monitor a frequency for activity
while drawing as much as 400% less current than is required for normal
squelched reception. This is done by removing power from all
circuits (except a timer and the display) for programmable intervals.
Between these intervals, the receiver is enabled for 30ms to check the
displayed frequency for activity. "SAVE" is displayed below the
secondary frequency when the Power Saver feature is enabled. During
power saving, "SAVE" flashes on and off..
When a signal appears the receiver functions normally. However, if the
carrier drops for more than about 3 seconds, power saving resumes
automatically. If the PTT switch is closed at any time during power
saver operation, the transmitter activates as usual. If no station responds
to the transmission within 3 seconds after releasing the PTT switch,
power saving resumes.
When "SAVE" is not displayed power saving is disabled. To enable it,
press F/M and then SAVE(4), and wait a few seconds. Normally you will
want to keep it enabled, but if you use the FT-470 for packet you will
want it disabled, as it might otherwise interfere with packet reception.
To disable power saving, press F?M followed by SAVE(4) and then the
"0" key quickly ("OFF" will be displayed for a few seconds before the
display returns to the operating frequency.
Remember that power saving only occurs when the squelch is closed

(BUSY/TX lamp off). As shipped from the factory, power saving provides
a 1:6.7 duty cycle (30ms receive, 200ms sleep}. This ratio can be
reprogrammed from the keypad for 1:1 to 1:33.3. To do this, first select
the ratio you want from the chart below and note its corresponding key
number, then press F/M, SAVE(4) and the key number you selected
(quickly). The new save time (in seconds) will be displayed before the
display returns to the operating frequency. Turning the transceiver off
does not affect the state (or programmed ratio) of the power saver.

EXAMPLE: to program a save ratio of 10:1 -

Press F/M followed by SAVE(4) and then (immediately) the 5 key.
The display briefly shows 0.30 indicating 300 ms save time.

APO (Automatic Power-Off)
This feature automatically puts the transceiver to sleep if the keypad/DIAL
knob or PTT button is not used for a selectable period of 10, 20
or 30 minutes. One minute before going to sleep, a warning melody will
sound ([ - -., I -, 2 j I ,2.: ': -2 I), and the "APO" letters along the
bottom of the display will begin to blink. If no key is pressed within the
next minute, the display will change to "OFF", with the "APO" blinking. If
power saving is also enabled, "SAVE" will appear to the left of "APO",
even though power saving is NOT active in this condition.
"APO" appears at the bottom of the display whenever the APO feature
is enabled. To toggle it on and off, press F/M and then APO(5).
To check the current setting of the APO timer, turn off the transceiver
and then press and hold the "5" key while turning it back on. The display
will show the current timer setting (in minutes) before changing to the
frequency display. If you want to change the timer setting, turn the
transceiver off again, and then press and hold either the "1", "2" or "3"
key, for 10-, 20- or 30-minute APO time, respectively, while switching
the transceiver back on.

DTMF Memories
The FT-470 provides ten memories, numbered 0 through 9, for storage
of DTMF tone sequences of up to 15 digits each, allowing instant replay
of commonly used remote DTMF control sequences or telephone numbers to be
used on autopatching systems.
A special mode must be activated to use the DTMF memory features.
This mode is toggled on and off by pressing F/M and then the
DTMF(CALL) key at the top left corner of the keypad. "DTMF" appears
at the upper right corner of the display when this mode is active.

.
To store a DTMF memory:
(1) Activate the DTMF. memory mode as just described.
(2)
Press and hold the F/M key for second (until the second beep
sounds).
(3)
Within 5 seconds of step (2), press a numbered key corresponding
to the DTMF memory number you want to store. The
display will change to the following:
selected DTMF memory number (0-9)

serial digit number (01 to 15) in this memory
code stored in this digit
DTMF codes are displayed as 0=9, A, b, C, d, E (for a), F (for #)
and "-" for empty (none stored).
(4)
Again press and hold F/M for ,}-second, and then key in the
numbers of the DTMF sequence to store. As you do so, the serial
digit number in the center of the display will increment automatically
as the entered code is displayed at the right. If you make
a mistake press the PTT switch and repeat this step.
(5)
After entering the desired DTMF sequence, press the
DTMF(CALL) key briefly, and then press the numbered key corresponding
to the memory number stored, to replay the stored
codes in the loudspeaker.
(6)
Turn the DIAL knob to select another DTMF memory to store,
if desired, and repeat steps (4) and (5).
(7)
Press the DTMF(CALL) button to return to the frequency
display.

.
To recall a stored DTMF memory on the air, first make sure the DTMF
memory mode is activated ("DTMF" is displayed). Then close the PTT
switch and press the number of the DTMF memory to transmit.
CAUTION: When the DTMF memory mode is active, the keypad cannot
be used to transmit individual DTMF codes. If you do not have the
required DTMF sequence stored in memory, turn the DTMF memory
mode off [F/M and then DTMF(CALL)], and then enter the DTMF digits
individually.

System Reset
To reset all programmable features and settings to their factory defaults,
turn off the transceiver and then press and hold both the VFO and MR
keys while switching it back on.

.
In Case of Problems
The basic features of this transceiver are not complicated, but it is
possible to get lost, at least until you have had the charicteristics of the
functions of the keypad and display. If the display doesn't work at all,
check the power switch (VOL control), and if necessery, remove the battery
pack and check that the contacts are clean. Ifeverything appears to be
physically in order, recharge or replace the batteries.

The display includes enough symbols and function indicators to let you
know what is going on as long as power is applied, so it is well worthwhile
to study the display diagram on page 7 carefully. For example, if
the frequency display changes unexpectedly when you transmit (or if
Err appears), check for a small + or - along the top of the display
(just right of center), indicating that repeater shift is active. Also, if
only a few seemingly non-sensical digits appear, try switching the set off
and back on to clear any special display modes, such as tone squelch,
repeater offset, channel step or DTMF memory setting.

Most illegal commands will cause two beeps to sound. If pressing a key
appears to do nothing, first check for a small "Ptt" or an "I" in reverse
type at the lower left, which indicates the Ptt or keypad is locked. If so,
press F/M and then PTT LOCK(9) or LOCK(6) to unlock the PTT switch
or keys. If the "Ptt" or "I" is not there, press the F/M or CALL key,
which will terminate many partially entered commands. If you still
cannot enter data, check the TX indicator to see if it is red or orange,
indicating that the transceiver is transmitting. Releasing the PTT switch
should return the set to receive. If still nothing happens, switch the
transceiver off, and then back on.

If you find the stored data is definitely non-sensical or far from what
you want, try the System Reset procedure described on the previous
page.

To avoid confusion resulting from inadvertent key presses, set the
keypad lock on [press F/M and LOCK(6)] if you set the transceiver down
while it is on, and then remember to set the lock back off when you wish
to enter data.
