HTX-202  (190-1120)             Preparation            Faxback Doc. # 15719

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.  Then 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.
