performance with packet systems.

16 Frequency Memories - include one calling-frequency memory,
three priority-frequency memories, and
12 standard memories.

Individually Programmable Repeater - let you program a different repeater
Offsets offset frequency for each memory, and
default repeater offset for manually-
tuned frequencies.

Sub-audible Tone Transmit and - let you transmit the Sub-audible tone
Decode (CTCSS) required by some repeaters, and also
lets you set a Sub-audible tone that
your transceiver must receive to open
squelch.

Touch-Tone Page - lets you set a sequence of up to five
touch-tones your transceiver must
receive to sound an alert tone to open
the squelch.

16-Digit DTMF Memory Sequences - lets you transmitt all touch tones
(0-9, #, *, and A-D).

Dual Power Transmitter - lets you select between 1-Watt and
6-Watt to preserve battery power.

Five DTMF Memory Sequences - lets you store five touch-tone
sequences of up to 15 digits each so
that you can quickly transmit the
sequences you commonly used to
activate repeaters or autopatches, or
other stations equipped with touch-
tone page.

Multi-Function Scanning - lets you scan the standard memories,
priority frequency memories, or a
frequency range, and automatically
resume scanning when the carrier
drops, resume scanning after 10
seconds, or stop scanning when carrier
is detected.

Programmable Frequency Step - lets you set the frequency step for
tuning or scanning to 5, 10, 15, 20,
25, 50, or 100 kHz.


preparation

You can operate your transceiver from any of the following sources:

Rechargeable power pack (supplied with charger)

Six alkaline AA batteries (using the supplied alkaline pack)

Vehicle battery power (using optional adapter)

OPERATING FROM THE RECHARGEABLE POWER PACK

You can use the supplied rechargeable power pack to power your transceiver.
This power pack provides 7.2 volts and can operate your transceiver at 2.5
watts(typical power) with the low power button out. As supplied, the power
pack is fully discharged. You need to fully charge the pack using the
supplied charger before you operate the transceiver from the rechargeable
pack. Follow these steps to charge the pack.

1. If the pack is attached to the transceiver, turn off the transceiver.
Do not operate the transceiver while charging the pack.

NOTE: You can remove the power pack from the transceiver to charge it,
and operate the transceiver from one of the other power sources.

2. Plug the supplied charger's barrel plug into the CHARGE jack on the
back of the power pack.

3. Plug the charger into a standard AC outlet. The CHARGE indicator
lights.

It takes about 10 hours to charge the power pack.

When power is low, BATT appears on the display when you press PTT. You
can buy extra power packs through your local Radio Shack store.

NOTES: Nickel-cadmium batteries deliver more power if you occasionally let
them completely discharge. To do this, use the transceiver until
BATT appears on the display when you push the PTT. Then fully
charge the batteries. If you do not occasionally do this, the
batteries temporarily lose the ability to deliver full power. Also,
to ensure a full charge, be sure the batteries are at room
temperature (above 65 degrees F) when you charge them. Cold
batteries do not fully charge.

Even when the battery is fully charged, the battery power meter will
not read full scale. However, it will indicate full scale when being
powered from the cigarette lighter adapter.

CAUTIONS: To prevent permanent nickel-cadmium power loss, never charge the
power pack in an area where the temperature is above about 80
degrees F.

Never use a charger other than the one supplied to charge the
power pack. Even chargers with the same voltage and current
ratings could permanently damage the transceiver or the power
pack. You can order a replacement charger at your local Radio
Shack store.

USING ALKALINE BATTERIES

You can operate the transceiver from 6 AA alkaline batteries (not
supplied) using the supplied alkaline battery holder. This battery holder
supplies 9 volts and can operate your transceiver at 4 watts (typical
power) with the low power button out. Follow these steps to load or
replace batteries in the alkaline battery holder.

1. Hold the outer battery holder case and push down on the center of the
battery holder.

2. Remove old batteries, if necessary, and install six fresh AA alkaline
batteries, observing the correct polarity as indicated by the markings
(+ and -) in the battery holder.

3. Press the battery holder into the battery holder case.

When power is low, BATT appears when you press PTT. Be sure to use six
fresh AA alkaline batteries. Never mix different types of batteries, and
never mix old and new batteries.

OPERATING FROM VEHICLE BATTERY POWER

You can operate the transceiver from vehicle battery using a DC power cord
(Radio Shack Cat. No. 270-1533). This cord supplies a 13.8 volts (typical)
to your transceiver and can operate your transceiver at 6 watts (typical
power) with the LOW POWER button out. Follow these steps to operate from
the vehicles battery power.

1. Plug the power cord's barrel plug into the transceiver's EXT DC jack.

CAUTION: Never plug the power cord into the rechargeable power pack's
CHARGE jack. Doing so can damage the power pack and the
transceiver.

2. Plug the power cord's cigarette-lighter plug into your vehicle's
cigarette-lighter socket.

If the transceiver does not operate, remove the power cord's plug from the
cigarette-lighter and check for debris. Clean the socket, if necessary,
and try again.

OPERATING FROM AC POWER

You can operate the transceiver from AC power using either the 1-amp 12
volt DC adapter(Cat. No. 273-1653) or our regulated 2.5-amp power supply
(Cat. No. 22-120). The 2.5-amp power supply lets you operate your
transceiver at 5 watts (typical power) with the low power button out and is
better isolated from 60 Hz noise. The 1-amp adapter connects very quickly
and requires no soldering but only operates your transceiver at about 2
watts with the LOW POWER button out.

Follow these steps to power the transceiver from the 1-amp, 12 volt DC
adapter.

1. Connect the barrel plug with the tip set to positive.

2. Insert the adapter's barrel plug into the transceiver's EXT DC jack.

CAUTION: Never insert the adapter's barrel plug into the rechargeable
power pack's CHARGE jack. Doing so can damage the power pack and
transceiver.

3. Plug the adapter into an AC outlet.

Follow these steps to power the transceiver from the regulated 2.5 amp
power supply.

NOTE: You need the following materials to use the regulated 2.5 amp power
supply:

Power supply (Cat. NO. 22-120)

Two-conductor 18-gauge wire (Cat. No. 278-5670

DC power connector (Cat. No. 274-1567)

Soldering iron and solder

Volt meter or multimeter

1. Cut the two-conductor wire to the length power cord you need.

2. Strip about 1/2 inch of insulation from each end of both conductors.

3. Solder one end of the wire to the DC power connector, with the red lead
connected to the center terminal, and the black lead connected to the
outer casing.

4. Melt a small amount of solder onto the other end of the wire. Then,
connect the red lead to the power supply's + terminal and connect the
black lead to the power supply's - terminal.

5. Plug in the power supply and turn it on. Use the meter to confirm you
have correctly wired the power connector so that the tip is + and the
case is -.

6. Turn off the power supply and plug the connector into the transceiver
EXT DC jack.

CAUTION: Never plug the power connector into the rechargeable power
pack's CHARGE jack. Doing so can damage the power pack and
the transceiver.

7. Turn on the power supply.

BACKUP BATTERY

Your transceiver uses a lithium battery to keep stored options in memory
when you disconnect the transceiver from a power source. This battery
should last 3 to 5 years, under normal conditions. When the transceiver
frequently displays ER1, the back up battery needs to be replaced.

NOTE: To clear the error, reset the transceiver. See "Resetting the
Transceiver."

The backup battery is not user-serviceable. Take the transceiver to your
local Radio Shack store to have the battery replaced by a Radio Shack
repair center.

This product contains a rechargeable nickel-cadmium (lead acid) battery.
At the end of the battery's useful life, it must be recycled or disposed of
properly. Contact your local, county, or state hazardous waste management
authorities for information on recycling or disposal programs in your area.
Some options that might be available are: Municipal curb-side collection,
drop-off boxes at retailers, recycling collection centers, and mail back
programs.

CONNECTING THE ANTENNA

Your transceiver comes with a flexible antenna. You must connect an
antenna to your transceiver before you transmit. The transceivers BNC
antenna connector is easy to connect other types of antennas. Radio Shack
stores sell a 5/8 wave magnetic mount antenna for mobile operation (Cat.
No. 19-210), a discone antenna (Cat. No. 20-013), and a center-loaded
telescoping whip antenna (Cat. No.20-006) that you can use with your
transceiver.

To use the supplied antenna, slip the antenna's connector over the BNC jack
and twist the antenna to lock it in place.

To use an external antenna, if necessary, attach the appropriate connector
adapter to the end of the antenna cable. Then, slip the connector over the
BNC jack and twist the connector to lock it in place.

WARNING: When installing or removing an outdoor antenna, use extreme
caution. If the antenna starts to fall, let it go! It could
contact overhead power lines. If the antenna touches the power
line, contact with the antenna, mast, cable, or guy wires can
cause electrocution and death! Call the power company to remove
the antenna. Don't attempt to do so yourself.

ATTACHING THE BELT CLIP

You can attach the provided belt clip to your transceiver. Use the
supplied screws.

ATTACHING THE HAND STRAP

Loop the supplied hand strap's key ring through the hand strap tab.

USING AN EXTERNAL MICROPHONE

You can use an external microphone with your, transceiver. When you
connect an external microphone, the internal microphone does not work, but
the internal PTT is not affected. If your microphone has a 3/32 inch(2.5
mm) submini plug, plug the microphone cable into the transceiver's MIC
jack.

USING AN EXTERNAL SPEAKER

In a noisy area, an external speaker, positioned in the right place, might
provide more comfortable listening. Radio Shack stores sell an extension
speaker (Cat. No. 21-549) and an amplified communication extension speaker
(Cat. No. 21-541). Plug the speaker cable's 1/8 inch(3.5 mm) mini plug
into the transceiver's SP jack. This disconnects the internal speaker.

For the most efficient operation when you carry the transceiver on your
belt, connect a combination speaker/microphone (such as Cat. No. 19-310) to
your transceiver and hang the mic/speaker on your collar.

If your vehicle has a cassette player, you can easily connect your
transceiver to your vehicle's audio system using a CD-to-cassette adapter
(Cat. No. 19-1951) and a mono-to-stereo audio plug (Cat. No. 274-368).
Simply insert the adapter in your vehicle's cassette player, connect the
adapter's plug to the mono-to-stereo plug, insert the plug in the
transceiver's SP jack, and turn on your cassette player.

USING THE TRANSCEIVER WITH PACKET RADIO

You can connect your transceiver directly to a packet radio terminal mode
controller.

RESETTING THE TRANSCEIVER

When you first use the transceiver, if the transceiver displays ER1, or if
you ever want to reset the transceiver's options to the factory defaults
and clear all memories, follow these steps.

WARNING: This procedure clears all the stored information from the
transceiver.

1. Turn off the transceiver.

2. Press and hold down F+CLR. Then, turn on the transceiver.

USING THE LIGHT

Press L on the side of the transceiver to turn on the display light for
about 5 seconds. To turn the light off sooner, press L again. The light
stays on until you press L or turn off the transceiver.
Operation

SETTING SQUELCH AND VOLUME

Rotate VOLUME clockwise and SQUELCH counterclockwise until you hear a
hissing sound. Then, slowly rotate SQUELCH clockwise until the noise
stops. Leave VOLUME set to a comfortable level.

If the transceiver picks up unwanted weak transmissions, rotate SQUELCH
clockwise to decrease the transceiver's sensitivity to signals.

SELECTING A FREQUENCY

You can use any of three methods to select a frequency to communicate on.

Direct entry

Tune control

Scanning for frequencies

TUNING USING DIRECT ENTRY

Your transceivers transmits and receives on frequencies between 144.000
and 148.000 MHz. To quickly tune to a frequency, enter the frequency
using the keypad.

1. Turn on the transceiver.

2. Press VF.

3. Use the keypad to enter the last four digits of the frequency. For
example, to enter 146.940, press 6940.

NOTES: If you make a mistake, press CLR and repeat this step.

The transceiver rounds the last digit down to 0 or 5.

TUNING USING THE TUNE CONTROL

You can quickly tune to a nearby frequency by rotating TUNE on top of the
transceiver.

1. Turn on the transceiver.

2. Press VF.

3. Rotate TUNE counterclockwise to tune down or clockwise to tune up. The
transceiver tunes up or down one frequency step per click, see "Setting
the Frequency Rate."

SCANNING FOR ACTIVE FREQUENCIES

You can scan for activity on a frequency by pressing and holding down /\SC
or \/SC for at least 1 second. The transceiver begins to scan up or down
the full frequency range, and stops on active frequencies. To scan only a
selected frequency range press F+/\SC or F+ \/SC. See "Setting the Scan
Options" to see how to change the scanning range, the frequency step, the
scan resume condition, and the scan delay time. The following are the
factory presets for these options.

Frequency Step: 15KHz
Scan Resume Condition: Resumes scanning in 10 seconds, regardless of
absence or presence of a carrier.
Scan Delay: Not activated.
Scan limits: 144 MHz to 148 MHz

To stop scanning, press \/SC, /\SC, CA, PR, VF, or turn off the
transceiver.

SCANNING FOR A VACANT FREQUENCY

In some areas where the 2-meter band is being used heavily, you might have
trouble quickly finding a frequency not being used. To quickly scan for a
vacant frequency, press F+V - SC. The transceiver scans up or down from
the current frequency to the first unused frequency. To change the vacant
scan direction, see "Setting the Vacant Scan Direction."

RECEIVING TRANSMISSIONS

To receive transmissions, turn on the transceiver, adjust the volume and
squelch, and tune to a frequency.

TRANSMITTING

There are two basic types of communication you can use with this
transceiver. These types are sometimes referred to as SIMPLEX and DUPLEX.
With simplex transmissions, you transmit and receive on the same frequency.
With duplex transmissions, you transmit on one frequency and receive on
another. Duplex transmission is the communication type you use when you
communicate using a repeater. You transmit to the repeater on one
frequency (the input frequency), and the repeater retransmits the signal
at a different frequency (the output frequency).

CAUTION: Do not transmit if you do not have a Technician Class or higher
license issued by the FCC. Doing so is illegal.

Follow these steps to communicate using simplex communications.

1. Turn on the transceiver.

2. Select the desired frequency.

3. If + or - is on the display, repeatedly press F & + / - until neither
symbol appears.

4. Press LOW POWER so that the button is down. In this position, your
transceiver transmits at about 1 watt.

5. Begin communications.

If the other party advises that you need to improve your signal (QRO),
press LOW POWER so that the button is up. In this position, your
transceiver transmits at the highest power it can, depending on the power
source. Remember to switch back to low power whenever possible, to comply
with the FCC rules that require you to use the minimum power necessary to
maintain communications.

Follow these steps to communicate using duplex communications.

1. Turn on the transceiver.

2. Tune to the desired receive (output) frequency.

3. If the transmit (input) frequency is 600 kHz ABOVE the receive
frequency, press F+ +/- so that the + appears in the display. If the
transmit frequency is 600 kHz BELOW the receive frequency, press F+ +/-
so that - appears on the display. If the frequency separation is not
600 kHz, either set a new default frequency or store the frequency pair
in one of the scanner's memories (See "Using Memory Channels" and
"Setting the Duplex Separation").

LOCKING THE KEYPAD

To lock the transceiver's keypad so that you do not accidently change a
setting, press F+LOCK. LOCK appears on the display. This locks all front-
panel buttons and the tune control. The PTT, VOLUME, and SQUELCH still
operate. To release the lock, press F+LOCK again.

SETTING THE KEY ENTRY BEEP

Each time you press a key, the transceiver sounds a beep. To turn off the
beep, press F+BEEP. The key beep does not sound this and subsequent key
presses. To turn on the key beep, press F+BEEP again.

REVERSING THE OFFSET

To reverse the transmit and receive frequencies when you are operating
duplex, press F+REV. For example, if you are set to 146.94 with a - offset
pressing F+REV makes the transceiver receive on 146.14 and transmit on
146.94.

USING MEMORY CHANNELS

Your transceiver has 16 memory channels in three groups.

One calling-frequency memory

Three priority-frequency memories

12 standard memories

USING THE CALLING-FREQUENCY MEMORY

The calling-frequency memory provides a single memory that you can quickly
jump to at any time. Follow these steps to save a frequency in the
calling-frequency memory.

1. Press VF.

2. Tune to the frequency you want to save.

3. Press CA.

4. If the frequency is for a repeater that requires subaudible tone access
or if you want to use incoming subaudible tone squelch with frequency,
press F+T-SQL so that T-SQL appears on the display.

NOTE: If you turn on T-SQL you must correctly set both the transmit
subaudible tone as described in steps 8 through 11.

5. Press and hold down F+M-WR for at least 1 second.

The transceiver stores the tuned frequency in the calling-frequency
memory, plus the frequency separation (for duplex operation) and
subaudible transmit and receive tones. For more information about
subaudible tones, see "Using Subaudible Tone Squelch" (CTCSS)."

6. If you want to set a different transmit frequency or change the
subaudible tones, press F+M-SET. The transceiver displays TF followed
by the transmit frequency.

7. Rotate TUNE to change the transmit frequency.

8. To set a transmit subaudible tone frequency, press \/SC. The
transceiver displays TC followed by the transmit subaudible tone
frequency.

9. Rotate TUNE to change the transmit frequency.

NOTE: If you do not want to transmit subaudible tone, rotate TUNE to
set the transmit subaudible tone to OFF.

10. To set a receive subaudible tone frequency, press \/SC. The
transceiver displays RC followed by the receive subaudible tone
frequency.

11. Rotate TUNE to set the receive subaudible tone frequency.

NOTE: If you do not want to use incoming tone squelch, rotate TUNE
to set the receive subaudible tone to OFF. Otherwise, you do
not hear transmissions unless the subaudible tone is present.

12. Press the PTT to save the settings and return to the calling-
frequency memory display.

To use the calling frequency memory, press CA at any time. The transceiver
immediately goes to the calling frequency and sets the transmit frequency,
subaudible tones, and tone squelch to the settings you programmed. To
return to the previous settings, press CA again.

USING THE PRIORITY-FREQUENCY MEMORIES

The transceiver has three priority-frequency memories. The transceiver can
periodically scan these frequencies during manual, calling-frequency
memory, or standard memory operation. Follow these steps to store a
frequency in the priority-frequency memories.

1. Press press VF and tune to the frequency you want to save.

2. Press F and rotate TUNE until either P1, P2, or P3 appears to the left
of the tuned frequency.

3. If the frequency is a repeater that requires subaudible tone access or
if you want to use subaudible tone squelch with this frequency, press
F+T-SQL so that T-SQL appears on the display.]

4. Press F+M-WR for at least 1 second to store the tuned frequency in the
selected priority-frequency memory.

5. To change the frequency separation or subaudible tones, press PR and
rotate TUNE to select the priority-frequency memory you want to change.
Then, refer to steps 6 through 12 under "Using the Calling-Frequency

to oFF Transmit time-out
Lb 4 Priority-frequency channel lookback time
Ar oFF Touch-tone auto-reply

SETTING THE DUPLEX SEPARATION DEFAULT

The duplex separation default (offset) controls the offset between the
transmit frequency and the receive frequency when you use the transceiver
in duplex mode, as with a repeater. Typically, on the 2-meter band,
repeaters receive at a frequency 600 kHz lower or higher than they
retransmit (repeat) on. For example, if a repeater's input frequency is
146.340 MHz, its output frequency is 146.949 MHz. The following is a list
of the most commonly used repeater pairs.

INPUT FREQUENCY OUTPUT FREQUENCY

146.O7 MHz 146.67 MHz
146.13 MHz 146.73 MHz
146.16 MHz 146.76 MHz
146.22 MHz 146.82 MHz
146.25 MHz 146.85 MHz
146.28 MHz 146.88 MHz
146.31 MHz 146.91 MHz
146.34 MHz 146.94 MHz
146.37 MHz 146.97 MHz
146.40 MHz 147.OO MHz

To operate with a repeater, you must transmit on the repeater's input
frequency and receive on the repeater's output frequency. If you
frequently use a repeater that does not have a 600 kHz offset, we recommend
you program the repeater frequency into one of the transceiver's memories.
You can override the default offset for each memory.

To change the default offset, follow the steps in "Understanding the
Configuration Menu." to display the oS menu item, and rotate TUNE to change
the offset. The transceiver lets you set the offset to be in the range
from 0 MHz to 4 MHz in steps as set by the frequency step option.

USING SUBAUDIBLE TONE SQUELCH (CTCSS)

Some repeaters require that you transmit subaudible tone to key-up the
repeater. You can set your transceiver to transmit any of the 38 standard
subaudible tones. You can also limit incoming calls by setting your
transceiver to open the squelch only when someone transmits a subaudible
tone you set.

---------------- ----------------
| tc oFF | | rc oFF |
---------------- ----------------

To set a subaudible transmit tone, follow the steps in "Understanding
Configuration Menu" to display tc. Then, rotate TUNE to select the
subaudible tone. If you do not want to transmit a subaudible tone, rotate
TUNE to select OFF.

To set a subaudible receive tone, follow the steps in "Understanding the
Configuration Menu" to display rc. Then, rotate TUNE to select the
subaudible tone. If you do not want to use the receive subaudible tone
squelch, but are using transmit subaudible tone to activate a repeater,
rotate tune to select OFF. Otherwise, you only hear transmissions that
have the correct subaudible tone when you activate tone squelch.

To turn on the subaudible tone feature, press F+T-SQL. When you transmit,
the transceiver includes the subaudible tone in the signal. To receive,
the incoming signal must have the correct subaudible tone. You can
override the default subaudible tones for any memory.

SETTING SCAN OPTIONS

Several configuration menu items control how your transceiver operates
when you scan frequencies or memories. The following sections describe how
to set the frequency step rate, the scan condition, the scan delay
duration, and the scan limits.

SETTING THE FREQUENCY STEP RATE

The frequency step rate affects the scanning mode, the TUNE control, and
/\SC or \/SC tuning. The factory default for the frequency step is 15kHz.
Each time you rotate TUNE one click or \/SC or /\SC the frequency
changes by 15 kHz. When scanning, the transceiver scans up or down 15 kHz
step. To change the frequency step rate, follow the steps in
"Understanding the Configuration Menu" to display the Sr menu item, and
rotate TUNE to change the frequency step rate. You can set the step rate
to 5, 10, 15, 25, 50, or 100 kHz.

SETTING THE SCAN RESUME CONDITION

When you have set the transceiver to receive either standard memories or VF
mode, the transceiver stops whenever it encounters a signal strong enough
to break squelch. At the factory setting, the transceiver resumes scanning
in 10 seconds, regardless of the of the presence of a continued signal.
You can set the scan resume configuration item to one of the following.

ti Resumes scanning in 10 seconds
cr Resumes scanning after the carrier drops and the scan delays
expires (See "Setting the Scan Delay.")
SE Does not resume scanning

To change the resume condition, follow the steps in "Understanding the
Configuration Menu" to display Sc. Then, rotate TUNE to select the resume
condition.

NOTE: The resume option does not affect the priority scan. Priority
scan always resumes scanning after the carrier drops.

SETTING THE DELAY DURATION

When you set the scan resume condition to cr (carrier), the transceiver
resumes scanning after the carrier drops. The scan delay option lets you
set the transceiver to pause before resuming, so you can hear any reply.
The factory default for this option is 2 seconds.

To change the scan delay duration, follow the steps in "Understanding the
Configuration Menu" to display Sd. Then, rotate TUNE to select the scan
delay duration. You can set the delay to 0.5, 1, 2, or 4 seconds.

NOTE: The scan delay option also affects priority scan.

SETTING THE SCAN LIMITS

When you press F+\/SC or F+/\SC the transceiver scans only those
frequencies within a range you set with scan limit options. To set the
scan limits, follow the steps in "Understanding the Configuration Menu" to
display S1. Use either TUNE or the key pad to enter one of the frequency
limits. Then, press \/SC to display S2 and enter the other frequency
limit. You can enter the higher frequency as either limit.

SETTING THE VACANT SCAN DELAY

The transceiver's factory default for vacant scan is to scan down until it
finds an unused frequency. To change the vacant scan direction, follow the
steps in "Understanding the Configuration Menu" to display ud. Then,
rotate TUNE to select either UP or DN.

USING THE POWER SAVE FEATURE

To set the transceiver to save power press F+SAVE so that SAVE appears on
the display. In the power-save mode, the transceiver turns on the receiver
for about 32 milliseconds to check for any activity, and then turns off the
receiver for the time you set with the power-save configuration setting.
The factory default for this setting is to use only 1/16 normal power. To
change the power save setting, follow the steps in "Understanding the
Configuration Menu" to display PS. Then, rotate TUNE to select the power
save setting. You can set the power-save setting to 1-2, 1-4, 1-8, or 1-16
(1/2, 1/4, 1/8. or 1/16 normal power usage.

Press F+SAVE again to turn off power save. Power save temporarily turns
off while scanning.

PREVENTING TRANSMISSIONS

To prevent any transmissions using the transceiver, turn on the transmit
inhibit function. To turn on this function, follow the steps in
"Understanding the Configuration Menu" to display tE. Then, rotate TUNE to
select ON. To enable transmissions, set this option to OFF.

LIMITING TRANSMISSION DURATION

When you communicate on the 2-meter band, you should keep your transmission
as brief as possible. Most repeaters have built-in timers that limit
single transmissions to 3 minutes or less. You can set the transceiver to
stop transmitting and sound a beep if you exceed a set time limit with a
single transmission. To set a transmit limit, follow the steps in
"Understanding the Configuration Menu" to display to. Then, rotate TUNE to
select OFF 30, 60, or 120 seconds.

SETTING THE PRIORITY SCAN TIME

When you turn on PRIORITY scan, the transceiver checks the preprogrammed
priority-frequency memories periodically to see if there is any activity.
As factory set, the transceiver checks the priority-frequency memories
every 4 seconds. To change the PRIORITY scan time, follow the steps in
"Understanding the Configuration Menu" to display Lb. Then, rotate TUNE to
select 4, 8, 12, or 16 seconds.

USING TOUCH-TONE FEATURES

Your transceiver has a built-in 16-key touch-tone encoder. You can
manually send touch tones, or send tones from one of the five DTMF
memories. You can also set your transceiver so that it is silent until it
receives a specific sequence of touch tones.

MANUALLY SENDING TOUCH TONES

Some repeaters require you to enter a touch-tone code to key-up the
repeater. Also, some repeaters have autopatch devises that let you make
telephone calls through the repeater. To manually send the required tones,
press and hold down PTT. Then, enter the touch-tone digits.

NOTES: You must press D twice to send the D digit.

If the auto-reply feature is turned off, you can release PTT after
you enter the first digit. The transceiver continues to accept and
transmit the touch-tone signals until you pause at least 1 second.

STORING A DTMF MEMORY SEQUENCE

You can store frequently-used touch-tone sequences in the transceiver's
five DTMF memories. Each memory can hold up to 15 digits. Follow these
steps to store touch-tone frequencies.

1. Press and hold down F+DTMF for at least 1 second. The display changes
to show the first DTMF memory.

2. Press D. Then, press a digit from 1-5 to select one of the DTMF
memories.

3. Enter the touch-tone sequence. If the sequence is less than 15 digits,
press D, then press a digit from 1 to 5 to select a different DTMF
memory or press PTT to exit the DTMF memory store mode.

NOTE: To enter a D, press D twice.

TRANSMITTING A DTMF MEMORY SEQUENCE

To send a DTMF memory sequence, press and hold down PTT. Then, press D
followed by the DTMF memory number you want to transmit (1-5). The
transceiver transmit the tones.

The transceiver has two DTMF memory sequence transmit speeds. To switch
between fast and slow, press and hold down PTT. Then, press 0.

NOTE: If the auto-reply feature is turned off, you can release PTT after
you press D. Enter the DTMF memory number within 1.5 seconds.

USING DTMF SEQUENCE FOR PAGING

The DTMF squelch feature lets you set your transceiver to release squelch
only if it receives a specific touch-tone sequence. Follow these steps to
set the touch-tone sequence.

1. Press F+D-SQL for at least 1 second.

The transceiver displays the previous sequence or - if you have never
programmed a sequence.

2. Enter the sequence (up to five digits).

3. Press PTT to save the sequence.

To turn on the DTMF squelch, press F+D-SQL for less than 1 second. DTMF
appears on the display.

Your transceiver remains silent until it receives the correct touch-tone
sequence. Then, it beeps and returns to normal operation. To cancel DTMF
squelch, press F+D-SQL for less than 1 second so that the DTMF disappears
from the display.

AUTOMATICALLY SENDING A DTMF REPLY

You can set your transceiver to automatically transmit the touch-tone digit
(#) when you have enabled DTMF squelch and the transceiver receives the
correct touch-tone sequence. To turn on the DTMF auto-reply, follow the
steps in "Understanding the Configuration Menu" to display Ar. Then,
rotate TUNE to select on.

You should also set this option to on if you expect an auto reply from an
auto patch or another HTX-202 or other transceiver that has this feature.

Care and Maintenance

Your HTX-202 2-Meter Handheld Transceiver is an example of superior design
and craftsmanship. The following suggestions will help you care for your
transceiver so that you can enjoy it for years.

Keep the transceiver dry. If it does get wet, wipe it dry immediately.
Liquids can contain minerals that can corrode the electronic circuits.

Use and store the transceiver only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices and
distort or melt plastic parts.

Handle the transceiver gently and carefully. Dropping it can damage
circuit boards and cases and can cause the transceiver to work
improperly.

Keep the transceiver away from dust and dirt, which can cause premature
wear of parts.

Wipe the transceiver with a dampened cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the transceiver.

Modifying or tampering with your transceiver's internal components can
cause a malfunction and might invalidate its warranty and void your FCC
authorization to operate the transceiver. If your transceiver is not
performing as it should, take it to your local Radio Shack store.

Error Codes

Your transceiver has two error code displays. Refer to the following for
an explanation of each error code.

Er1: INTERNAL RAM ERROR

Er1 indicates the transceiver has detected an error in its battery-backed
up operation memory. This is the most commonly caused by a low lithium
backup battery, but can also be caused by static discharge, or a physical
shock. To clear the error--

1. Turn off the unit.
2. Press FUNCTION and CLR (the D key).
3. While holding these keys, turn unit on.

This will reset unit and clear memories.

If the transceiver frequently displays the error, have the battery replaced by
an authorized Radio Shack service center.


ER2:PLL UNLOCK ERROR

Er2 indicates the transceiver's PPL section has unlocked. Have the
transceiver repaired by an authorized Radio Shack service center.


Hints and Tips

This radio is likely to get an ERR2 when running off a cigarette lighter.
This is due to RF feedback which travels from radio to rubber duck to
power cord and back to radio. The best way to fix the ERR2 is to use an
external antenna.

When pressing f/3, it only comes up with a negative offset. In order to
come up with a positive offset, check the offset by entering VFO mode and
pressing function/8. The display reads os and a number. That number is
normally 600. It will not give any offset that puts it out of the legal
limits of 144-148 MHz.

This radio cannot be modified for expanded frequencies.
