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.
. 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.

. 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. 270-15 ). This cord supplies a 1 .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. 27 -165 ) 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.
. 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.
. 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 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. 20-01 ), 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 / 2 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( .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- 10)
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- 68).
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.

and 148.000 MHz. To quickly tune to a frequency, enter the frequency
using the keypad.

1. Turn on the transceiver.
2. Press VF.
. 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.
. 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.
. 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.
. 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
