MTX-103 VHF Marine Transceiver
(190-1004)                 Preparation                Faxback Doc. # 18754

CHARGING THE BATTERY PACK

The MTX-103 operates on a built-in rechargeable battery pack (supplied). 
You must charge the battery pack with the supplied battery charger before
you use it the first time and when BAT lights steadily.

You can charge the battery pack while it is detached from or while it is
attached to the transceiver.

To attach the battery pack, slide it onto the transceiver until the latch
clicks.

To remove the battery pack, push the battery pack latch in the direction
of the arrow, then slide the battery pack off the transceiver.

Follow these steps to charge the battery pack.

CAUTION:  Do not use the transceiver while the charger is connected.

1.  If the battery pack is attached to the transceiver, make sure VOLUME is
    turned fully counterclockwise so the transceiver is off.

2.  Pull out the CHG PWR jack plug on the bottom of the battery pack.  Plug
    the charger's barrel plug into the CHG PWR jack, then connect the
    charger to a standard AC outlet.

NOTE:  Charging time is 14 to 16 hours.

CAUTIONS:  To prevent permanent battery power loss, never charge the
           batteries in an area where the temperature is above about 80
           degreesF.  The charger does not operate at all at temperatures
           below 32 degreesF or above 113 degreesF.

           Never use any other charger to recharge the transceiver's
           battery pack.  This could permanently damage your transceiver
           or the battery pack.

Important:  This transceiver uses a rechargeable nickel-cadmium battery
            pack.  At the end of the battery pack'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
            mailback programs.

CONNECTING THE ANTENNA

CAUTION:  To prevent damage to your transceiver, you must connect an
          antenna before you operate it.

1.  Position the BNC antenna connector over the antenna jack on the top
    of the transceiver.

2.  Place the slots in the antenna's connector over the tabs on the antenna
    jack, squeeze the base of the antenna, and push down and turn the
    antenna's base clockwise until it locks into place.

Instead of the supplied antenna, you can connect an optional antenna.  The
BNC antenna jack on your transceiver makes it easy to connect a variety of
antennas, such as an external mobile antenna or an outdoor base antenna,
available at your local Radio Shack store.

CAUTION:  Never connect an antenna that is not specifically tuned for the
          transceiver's frequency range (156.025-162.275 MHz).

WARNING:  Use extreme caution when installing or removing a base station
          antenna.  If it 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.  Do not attempt to do so yourself.

USING AN EARPHONE

To listen privately or to hear better in a noisy area, remove the plug from
the SPK jack on the right of the transceiver and plug a monaural earphone
(such as Cat. No. 33-175) into the jack.  This automatically disconnects
the internal speaker.

USING AN EXTERNAL SPEAKER/MICROPHONE

An external speaker/microphone (such as Cat. No. 19-310) can make it easier
to use the transceiver when you clip it to your belt.  Remove the plugs
from the MIC and SPK jacks.  Then plug the speaker/microphone's connector
into the jacks.  This automatically disconnects the internal speaker.

USING THE WRIST STRAP

Clip the supplied wrist strap to the wrist strap tab, as shown.  Then
simply slip the strap over your hand.

USING THE BELT CLIP 

You can use the supplied belt clip to make the transceiver easier to use
when you are on the go.  Use the two supplied screws to attach the belt
clip to the transceiver.  Slide the belt clip over your belt or waistband.
