Do not transmit with high output power for extended periods.
The
transceiver may overheat.* do not modify this transceiver
unless instructed
by this manual or by kenwood documentation.
Do not expose the transceiver to long periods of direct sunlight
nor place the
transceiver close to heating appliances.
Do not place the transceiver in excessively dusty areas,
humid areas, wet
areas, nor on unstable surfaces.
If an abnormal odor or smoke is detected coming from the
transceiver, turn
off the power immediately. Contact a kenwood service station
or your
dealer. The transceiver is designed for a 13.8 v power source.
Never use a
24 v battery to power the transceiver.
#1 PREPARATION FOR MOBILE AND FIXED STATION OPERATION
#1.1 Mobile installation
Install the transceiver in a safe, convenient position inside
your vehicle that
minimizes danger to your passengers and yourself while the
vehicle is in
motion. For example, consider installing the transceiver under
the dash in
front of the passenger seat so that knees or legs will not
strike the radio
during sudden braking of your vehicle. Try to pick a well-ventilated
location
that is shielded from direct sunlight.
Installation example
Use the supplied mounting bracket to install the transceiver
inside your
vehicle. To enjoy the best viewing angle, you can position
the transceiver in
the bracket in a number of ways as shown below.
Installation steps;
I Install the mounting bracket in the vehicle using the supplied
flat washers
and self-tapping screws. There are 4 washers and 4 screws
supplied. The
bracket can be mounted with the bracket opening for the transceiver
facing
down for under dash mounting, or with the opening facing up.
The bracket
must be installed so that the 4 screw holes on the edge of
each bracket side
are facing forward.
2 Position the transceiver, then insert and tighten the supplied
hexagon
sems screws and washers. There are 2 screws and 2 washers
supplied for
each side of the bracket. Double check that all hardware is
tightened to
prevent vehicle vibration from loosening the bracket or transceiver.
#1.2 Dc power cable connection
Mobile operation
The vehicle battery must have a nominal rating of 12 v. Never
connect the
transceiver to a 24 v battery. Be sure to use a 12 v vehicle
battery that has
sufficient current capacity. It the current to the transceiver
is insufficient, the
display may darken during transmission, or transmit output
power may drop
excessively.
1 Route the dc power cable supplied with the transceiver
directly to the
vehicle's battery terminals using the shortest path from the
transceiver'.
If using a noise filter, it should be installed with an insulator
to prevent it from
touching metal on the vehicle.
It is not recommended to use the cigarette lighter socket
since some
cigarette lighter sockets introduce an unacceptable voltage
drop.
It the power cable must be routed through a hole in the vehicle
chassis or
body, for example in the firewall at the front of the passenger
compartment,
use a rubber grommet to protect the cable from abrasion, Dismantle
the
fuse holder to pass the cable through the firewall.
The entire length of the cable must be dressed so it is isolated
from heat
and moisture.
2 After the cable is in place, wind heat-resistant tape around
the fuse holder
to protect it from moisture. Tie down the full run of cable.
3 To prevent the risk of short circuits, disconnect other
wiring from the
negative h battery terminal before connecting the transceiver.
4 Confirm the correct polarity of the connections, and attach
the power cable
to the battery terminals; red connects to the positive (+)
terminal, black
connects to the negative (-) terminal.
Use the full length of the cable without cutting off excess
even if the cable is
longer than required, in particular, never remove the fuse
holders from the
cable.
5 Reconnect any wiring removed from the negative terminal.
6 Connect the dc power cable to the transceiver's power supply
connector.
Press the connectors firmly together until the locking tab
clicks. Fixed station
operation
In order to use this transceiver for fixed station operation,
you will need a
separate 13.8 v do power supply that must be purchased separately.
The
recommended current capacity of your power supply is 12 a.
1 Connect the dc power cable to the regulated dc. power supply
and check
that polarities are correct(Red: positive, black: negative).
Do not directly
connect the transceiver to an Ac outlet! Use the supplied
dc power cable to
connect the transceiver to a regulated power supply. Do not
substitute a
cable with smaller gauge wires.
2 Connect the transceiver's dc power connector to the connector
on the dc
poinder cable. Press the connectors firmly together until
the locking tab
clicks.
Note; For your transceiver to fully exhibit its performance
capabilities, the
following optional power supply is recommended: Ps -33 (20.
5 a, 25% duty
cycle. Before connecting the dc power supply to the transceiver,
be sure to
switch the transceiver and the dc power supply off Do not
plug the dc power
supply in to an ac outlet until you make all connections.
Replacing fuses
If the fuse blows, determine. the cause then correct the
problem, after the
problem is resolved, then replace the fuse. If newly installed
fuses continue
to blow, disconnect the power cable and contact your dealer
or the nearest
service center for assistance.
Fuse in Transceiver 15a
Supplied accessory Dc power cable 20A
Caution Only use fuses of this specified type and Rating.
Note: If you use the transceiver for long periods when the
ve hicie battery is
not fully charged, or when the engines is off the battery
may become
discharged, and will not have sufficient reserves to start
the vehicle, avoid
using the transceiver under these conditions.
#1.3 Antenna connection
Before operating, you must first install an efficient, well-tuned
antenna. The
success of your installation will depend largely on the type
of antenna and
its correct installation. The transceiver can give excellent
results if the
antenna system and its installation is given careful attention.
Your choice of antenna should have a 50 ohm impedance to
match the
transceiver input impedance. Use low-loss coaxial feed line
that also has a
characteristic impedance of 50ohms. Coupling the antenna to
the
transceiver via feedlines having an impedance other than 50
q reduces the
efficiency of the antenna system, and can cause interference
to nearby
broadcast television receivers, radio receivers, and other
electronic
equipment.
Caution.
Transmitting with out first connecting an antenna Or other
matched load
may damage the transceiver, Always connect the antenna to
the transceiver
Before transmitting. All fixed stations should be equipped
with a Lightning
arrester to reduce the risk of fire, Electric shock, and transceiver
damage,
#1.4 Accessory connections
External speakers
If you plan to use external speakers, choose speakers with
an impedance of
8 ohms. The external speaker jacks accept a @.5 mm (1/8")
diameter mono
(2-conductor)plug. Recommended speakers include the sp-sob
and Sp-41.
Microphone
To communicate in the voice modes, plug a 600 ohm microphone
equipped
with an 8-pin modular connector in to the modular socket on
the front panel
of the transceiver. Press firmly on the plug until the locking
tab clicks.
#1.5 Packet equipment connections
if you intend to use this transceiver for packet operation
you will need the
following equipment Personal computer with communications
software
Terminal node controller (tnc) Tnc power supply Rs-232c cable
6-pin mini
din plug (optional pg-5a)
For the data connector pins, refer to "packet Operation".
Note: Do not share a single power supply between the transceiver
and the
TNC Keep a wide separation between the transceiver and computer
as
practical to reduce noise-pickup by the transceiver One end
of the optional
PG-5A cable has no connector. Attach the appropriate connector
that
mates with the TNC.

power supply.
#4.2 Adjusting Volume
Turn the vol control clockwise to increase the audio level
and
counterclockwise to decrease the audio level.
#4.3 Adjusting Squelch
The purpose of squelch is to silence audio output from the
speaker when no
signals are present. When squelch is set correctly, you will
hear sound only
while a station is actually being received. The point at which
ambient noise
on a frequency just disappears, called the squelch threshold,
depends on
the frequency.
Turn the sol control clockwise to just eliminate the background
noise when
no signal is present.
#4.4 Selecting a Band
Press band selectto select the v.h.f or u.h.f band. PTT appears
above the
v.h.f or u.h.f frequency to sho which band you selected.
#4.5 Selecting Frequencies
Tuning control
Using the tuning control is convenient when you are with
in easy reach of
the transceiver front panel, and the frequencies to be selected
lie near the
current frequency.
1 Press VFO to select VFO mode.
2 Turn the tuning control to select a receive frequency.
Clockwise rotation
increases the frequency one frequency stop at a time. Counterclockwise
rotation decreases the frequency one step at a time. To change
frequencies
in steps of 1 mhz, press MHz first. Pressing mhz again cancels
the 1 MHz
function. To change in steps of 10 MHz, press F and Mhz first.
Pressing F
cancels the 1 0 MHz function. If you cannot select a particular
receive
frequency, the frequency step size needs to be changed. See"Changing
frequency step size" for further information. You can
also select frequencies
via the microphone keypad. See "keypad direct Entry".
Microphone Up an Down buttons
Using mic up or down for frequency selection is useful when
mobiling or any
time you are mot immediately inn front of the transceiver.
Press up or down once to change the receive frequency by
one frequency
step in the direction indicated by the button.
Pressing and holding either button causes the frequency@to
step
repeatedly in one direction until the button is released.

[mhz] (or [1-7 +
[mhz]) first.
#4.6 Transmitting
I When ready to begin transmitting, press and hold mic(Ptt]
and speak in a
normal tone of voice. "On air" and the rf power
meter appear.
Speaking too close to the microphone, or too loudly, may
increase distortion
and reduce intelligibility of your signal at the receiving
station.
The rf power meter shows the relative transmit output power.
2 When you finish speaking, release mic PTT
Selecting output power
It's wise, and required by law, to select the lowest power
that allows reliable
communication. If operating from battery power, lower transmit
power will
give you more operating time before a charge is necessary.
Reducing power
lowers the risk of interfering with others on the band.
Press Loww to select the transmit power you require.
Each time you press Low, the transmit power is changed from
high to
medium to low, then back to high again. The display shows
nothing for high
power, an M for medium and an L for low power.
Caution. Do not transmit with high output power for Extended
periods. The
transceiver may overheat and malfunction. Continuous transmissions
cause
the radiator to Overheat never touch the radio or in such
a situation.
Note: when the transmitter overheats because of ambient high
temperature
or continuous transmissions, the protective circuit function
to lower transmit
output power.
#5 MENU SET[UP

#6 OPERATING THROUGH REPEATERS
Compared to simplex communication, you can usually transmit
over much
greater distances by using a repeater Repeaters are typically
located on a
mountain top or other elevated location. Often they operate
at higher erp(
Effective radiated power) than a typical station. This combination
of
elevation and high ERP allows communications over considerable
distances.
Repeaters are often installed and maintained by radio clubs,
sometimes with
the cooperation of local businesses involved in the communications
industry. During emergencies, repeater networks can be a valuable
aid to
officials responsible for coordinating communications in a
community.
#6.1 Repeater access
Most amateur radio voice repeaters use a separate receive
and transmit
frequency. The transmit frequency may be higher or lower than
the receive
frequency but the difference in frequencies will be a standard
amount,
or"standard split". You can set a separate receive
and transmit frequency by
selecting the offset frequency and offset direction with respect
to the receive
frequency.
In addition, some repeaters may require the transceiver to
transmit a tone
before the repeater can be used. To transmit this required
tone, activate the
tone function and select a tone frequency. The required tone
frequency
depends on the repeater you are accessing.

Press [f], [shift].
Each time you repeat this key operation, the offset direction
changes from
simplex to + tp - and back to simplex. If the offset transmit
frequency falls
outside the allowable transmit frequency range, transmitting
is inhibited until
the transmit frequency is brought within the band limits by
one of the
following methods:
Move the receive frequency further inside the band.
Change the offset direction.
Note; while using a split memory channel transmission you
cannot change
the offset direction

Automatic Repeater Offset
This function automatically selects an appropriate offset
direction according
to the frequency that you select on the v.h.f band. The transceiver
is
programmed for offset direction as shown below- to obtain
an up-to-date
band plan for repeater offset direction, contact your national
amateur radio
association.
This complies with the standard arrl band plan. 144.0 to

6 Press menu again to exit menu mode.
#6.2 Reverse Function
When used while monitoring a repeater, the reverse function
allows you to
manually check the signal strength of a station accessing
the repeater. If the
station's signal is strong, it is best to move to a simplex
frequency to
continue the contact and free up the repeater.
Press reverse to toggle the reverse function on or off. The
receive frequency
and the transmit frequency are exchanged, R appears on the
display when
the function is on.
Note:
By pressing reverse places the transmit frequency outside
the allowable
trans"t frequency range, an error beep sounds when PTT
is pressed, and
transmission is inhibited.
If reverse would place the receive frequency outside the receive
frequency
range, an error beep sounds when reverse is pressed. No reversal
occurs.
Automatic repeater offset does not function while reverse
is on.
You cannot switch reverse on or off while transmitting.
Automatic Simplex Checker (asc)
This function automatically monitors the strength of the
signal you a re
receiving from the repeater. If the signal strength is high
enough to allow
direct contact without a repeater, an indicator on the display
begins blinking.
This alerts you to move off to a private frequency and release
the repeater
for other users.
I Hold rev for 1 s to switch the function on. The asc indicator
appears. While
direct contact is possible, the asc indicator banks.
2 To cancel asc, press rev. Note: When direct contact becomes
impossible,
the asc indicator stops blinking. Asc does not function if
your transmit and
receive frequencies are the same (simplex operation). ASC
does not
function while scanning. If you recall a memory channel or
the call channel
that contains that contains reverse on status, ASC is switched
off.
#7 MEMORY CHANNELS
in memory channels, you can store frequencies and related
data that you
often use. A total of 280 memory channels are available, 140
each for v.h.f
and u.h.f
You can also store a name for each memory channel. Using
this naming
function restricts the total number of memory channels to
180, but allows
you to select the ratio of channels between the v.h.f and
u.h.f bands, from
among 5 types. For more information, see "naming memory
channels".
#7.1 Simplex or split memory channel?
There are 2 methods of storing transmit/receive frequencies
and related
data in memory channels, depending on the relationship of
the transmit and
receive frequencies. You can use each memory channel either
as a simplex
channel or spit channel. Use as a split channel to store a
separate receive
and transmit frequency.
Simplex memory channels: Rx frequency = tx frequency Split
memory
channels: Rx frequency does not equal tx frequency
Note. Not only can you store data in memory channels. but
you can also
upgrade existing data with new data.
The data listed below can be stored in each memory channel:
Rx frequency
Tx frequency Tone frequency CTCSS frequency Tone or CTCSS
status
Frequency step Offset direction Reverse status DTSS code,
DTSS status

#7.2 VHF and UHFMemory Channel Ratio
You can change the ratio of memory channels between the V.h.f
and u.h.f
bands, from the factory default (90 channel search). Changing
the ratio
requires all memory channels to be cleared. So decide the
appropriate ratio
before storing data in memory channels.
The selectable ratios are as shown below: 90 and 90 in each
70 in one and
110 in the other 50 in one and 130 in the other 140 in each

#7.8 Call Channel
The call channel can be used to store any frequency and related
data that
you will recall often. The call channel can be programmed
with a simplex or
split frequency as well as related data that can be stored
in the memory
channels. No matter what mode the transceiver is in, the call
channel can
always be selected quickly. You may want to dedicate the call
channel as an
emergency channel within your group. In this case, the call
f0 scan will be
useful.
The default frequency stored in the call channel are 144

#8.2 Application Examples
The following are examples of how you might use Programmable
memory.
These examples may not represent applications useful to you,
but you will
understand the flexibility of this function.
Situation 1
You share your transceiver with other members in your family
or club.
However, each individual has personal preferences for how
they like to set
various functions. You have to keep changing many settings
each ti" you
use the transceiver,
Solution:
Because 4 pm channels are available, up to 4 persons can
separately
program the transceiver and store their customized environment.
Then each
person can quickly change to his or her favorite settings,
simply by recalling
a PM channel.
It is too much trouble to change the settings after somebody
else has
reconfigured them. So this application may avoid having a
feature-rich
transceiver but never using many useful features.
Situation 2
While operating mobile on the way to work every morning,
you prefer a
silent transceiver that does not interrupt the morning calm.
In addition, you
feel that a bright display is a waste of electricity in sunlight.
At night when driving home, you realize the beep function
truly serves a
purpose and you acknowledge it is nice to see a bright display
after dark.
Solution:
In two pm channels, store the same operating data such as
frequency,
offset, DTSS code, etc., and store different settings for
the display dimmer
and beep functions. Then you can quickly recall the best settings
for day or
night operating.
Situation 3
You cannot figure out how you can make the transceiver exit
the current
mode.
Solution
Simply recall pm channel 1 that contains an exact copy of
it he transceiver
default environment. You will not lose the contents any memory
channels.
#8.3 Storing Data in PM Channels
1 Confirm that the following conditions have been satisfied:
Both bands are
in the receive mode. Scan is not being used on either band,
Microphone

2 Select the desired band.
3 Select the desired frequency and related data(Tone, CTCSS,
DTSS, etc.)
using VFO mode.
4 If required, select another band, then select the desired
frequency and
related data.
5 Press f then PM
The pm channel numbers appear and blink.
6 Press 1 to 4 corresponding to the desired PM channel. The
selected
frequency and related data are stored in the Pm channel.
#8.4 Recalling PM Channels
1 press PM The pm channel numbers appear.
2 4 press 1 to 4 corresponding to the desired PM channel.
The contents of
the selected channel are recalled. The selected channel number
appears at
the left bottom of the display. To exit pm recall mode, press
PM then VFO
Note You cannot recall a pm memory channel while transmitting.
#8.5 Auto PM Channel Storing
After you recalled a pm channel, this function automatically
over writes the
current pm channel with the present operating environment
when: You recall
another pm channel. You press pm then VFO You switch off the
transceiver,

When Using With CTCSS and DTSS
While using CTCSS, scan stops and the squelch opens only
when received
signals contain the matching CTCSS tone,
While using DTSS, scan stops for any signals received However,
if the
signals do not contain the matching DTSS code, the squelch
does no( open.
When both CTCSS and DTSS are on, scan stops for signals that
contain
the matching CTCSS tone. However it the signals do not contain
the
matching DTSS code, the squelch does not open.
Note:
Remember to adjust the squelch threshold level before using
scan.
Always turn off monitor and page before using scan.
When using s-meter squelch, scan stops when the received signal
strength
matches or exceeds the s-meter setting. Scan resumes 2 seconds
after the
signal level drops below the s-meter setting.
#9.1 Visual Scan
While you are on the air, visual scan allows you to monitor
frequencies near
the current operating frequency. Visual Scan graphically and
simultaneously
shows how all frequencies in the selected range are busy.
You will see up to
14 segments, for each channel, that represent 7 s-meter levels
(2 segments
per level).
You determine the scan range by selecting the center frequency
and the
number of channels. The default number of channels is 49.

The v.h.f band, VFO mode, and a frequency in the range 118
mhz to
136 mhz were selected.
Depending on conditions, visual scan and the conventional
s-meter may
indicate different signal strength levels.
#9.2 Scan Resume Methods
Before using scans other than visual scan, it's necessary
to decide under
what condition you want your transceiver to continue scanning
after
detecting and stopping for a signal. You can choose time-operated
mode or
Carrier-operated mode. The default is time-operated mode.
Time-operated Mode
Your transceiver slops scanning after detecting a signal,
remains there for
approximately 5 seconds, and then continues to scan ever if
the signal is
still present.
Carrier-operated Made
Your transceiver stops scanning after detecting a signal
and remains on the
same frequency until the signal drops out. There is a 2 second
delay
between signal drop-out and scan resumption to allow time
for any
responding stations to begin transmitting.
Note:
Turing the tuning control clockwise, or pressing mic up after
a signal that
has stopped scan drops out, causes scanning to resume immediately
upward.
Tuning the tuning control counter clock wise, or pressing
mic down after a
signal that has stopped scan drops out, causes scanning to
resume
immediately downward.

#10 CONTINUOUS TONE CODE SQUELCH SYSTEM CTCSS
CTCSS uses a sub audible tone to control the squelch of transceivers
and
by this system you can reject signals from undesired stations.
Suppose
Station A, B and C are programmed with the same tone frequency.
The
squelch on Station A is only opened by B or C.
#10.1 Using CTCSS
1 Select the desired band.
2 Repeatedly press tone until "ct" appears. Each
time you press [tone], the
selection changes from no indication, to tone "T"
to "CT" and back to no
indication.
3 Select the desired CTCSS frequency. To select this, refer
to selecting a
tone frequency and follow steps 2 to 4.
4 When you are called: The squelch of your transceiver opens
only, when
the selected tone is received. When you make a call. Press
and hold mic
PTT.
Note.,
You can select a separate tone frequency for the gtcss and
tone functions.
When using DTSS or page with CTCSS, the squelch opens only
if the
correct tone is received and the received DTSS code or page
code matches
the code stored in your transceiver
If you select a high tone frequency, receiving audio or noise
that contains
the same frequency portions may cause CTCSS to function incorrectly.
To prevent noise from causing this problem, select an appropriate
noise
squelch level using the squelch control.
Automatic Tone Frequency ID
This function automatically identifies the incoming tone
frequency on a
received signal.
1 Hold tone for 1 second to activate the function- A tone
frequency display
replaces the frequency display and the 1 hz decimal begins
blinking. When
a signal is received, the transceiver beginsscanning through
all tons
frequencies in order to identify the incoming tons frequency.
When the
frequency is identified, a beep sounds, and the identified
frequency appears
and blinks. The identified frequency is programmed in place
of the currently
set CTCSS frequency.
2 Press any key to cancel the function.
#11 DUAL TONE SQUELCH SYSTEM DTSS
Dts$ provides a more refined method the squelch selectively
communicate

same 3-digit DTMF(Dual tone multi frequency) code is received
that is
programmed in this transceiver. You can select a 3-digit code
from among
1000 combinations, 000 to 999.
Note:
Be aware that audio DTMF tones from other transceivers near
you may be
picked up by ' your microphone- if so. this could prevent
the functions

Both the DTSS status and a DTSS code can be stored in a memory
channel
or the call channel. Further, when recalling either a memory
channel or the
call channel with DTSS status on while using the VFO with
page switched
on, page is given priority and the DTSS status switches off
DTSS and Repeaters
Pressing mic PTT transmits the DTSS signal after a Pressing
short delay.
When using repeaters with long response times, this delay
helps the
repeater avoid losing a portion of the DTSS code. The delay

transceivers that
have the same code programmed, opens.
Unlike DTSS, page allows you to choose whether you will call
a single
station or a group of stations. In addition, Page offers the
added benefit all
identifying who called you. When you are called with your
station code, the
calling station's code appears on the display. If called with
a Group code,
the group code appears.
Note: Be aware that audio DTMF tones from other transceivers
