PREPARATION
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.
Follow these steps to charge the battery pack.
Caution:
while the charger is connected.

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

Charging time is 14 to 16 hours.
Note:

19-10 04 .f m Pag e 6 Tues da y , Au gu s t 3, 19 99 9:1 1 A M
Cautions:
• To prevent permanent battery
power loss, never charge the batteries in an area where the temperature is above about 80 °F. The
charger does not operate at all at
temperatures below 32°F or
above 113°F.
• 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 mu nicipal 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 connec t 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 clock wise
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 connec t 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 powe r c omp any t o
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 f rom the
SPK
jack on the right of the t ransceiver
and plug a monaural earphone (such
as Cat. No. 33-175) into the jack. This
automatically disconnects t he 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

speaker/microphone’s connector into

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 suppli ed belt clip to
make the transceiver easier to use
when you are on the go. Use the t wo
supplied screws to atta ch the belt clip
to the transceiver. Slide the belt clip
over your belt or waistband.

When making a call using a marine
transceiver, you must follow these calling procedures.
• Channel 16 is the universal calling
and safety channel. Leave the
radio set to Channel 16, unless a
call is in progress on a different
channel.
• Listen to Channel 16 for at least 2
minutes before making a call on it
(to be sure the channel is not
already in use).
• Press the push-to-talk button to
talk; the TX indicator should light.
Release it to listen; t he R X indi cator should light when a transmission is received.
• When you are ready for the other
party to talk, end your sentence by
saying “over.”

CHANNEL ASSIGNMENTS
Each of the 78 two-way communication
channels and 1 8 rec ei ve- only ch annels
is reserved for a s pecific type of tran smission. Misuse of a channel is a violation of FCC regulations.
You can listen to any channel. But, with
the Ship Radio Station License that you
receive by filling out FCC Form 506, you
can only transmit on Channel 16 and
channels marked in t he list that follows
as “Non-Commercial” or “Public Co rrespondence (Public Corresp).”
Also, be sure to observe the ship-toship and ship-to-shore assignments of
the channels.
The USA and international marine
channels share the same channel numbers. They do not, however, always use
the same frequencies. Also, many of
the international channels use d ifferent
frequencies for transmitting and receiving on a particular channel. Be sure that
you set the
propriate position.
