MTX-120 VHF Marine Transceiver
(190-1050)                 Hints and Tips             Faxback Doc. # 39324

1.  Be sure that the USA/INT'L switch is set to the appropriate position.
    USA and international channels share the same channel numbers, but use
    different frequencies. See "Channel Assignment" on Faxback Doc. # 39326.

2.  Use the CHANNEL thumbwheels to select the desired channel.  The left
    wheel selects the first digit of the channel number; the right wheel
    selects second digit. To listen to a NOAA weather channel, set the left
    wheel to W and select 1-9 on right wheel.

3.  Press and hold the talk button to transmit, and release it to listen.

4.  Adjust the VOLUME control for the desired listening level.

5.  Adjust the SQUELCH control clockwise until the background noise just
    disappears.  This is the proper squelch setting.  If the setting is too
    high, you won't receive weaker signals.  If it is too low, you'll hear
    background noise all the time. If you are purposely trying to receive a
    very weak or distant station, set the SQUELCH control fully counter-
    clockwise.

6.  Set the 1W/5W switch to 1W for normal communication.  Set it to 5W for
    emergency or long distance communication.

To Increase the communication range:

    Orient the antenna vertically.

    Move the unit away from shielding caused by nearby structures.

    Raise the unit as high as possible over the surrounding terrain.

    Try an external antenna.

CAUTIONS:  Receiving excessively strong signals might cause damage to the
           receiver.  Do not use the unit close to a base station antenna
           or less than twenty inches from another unit.

           Transmission without an antenna connected might cause damage to
           the transmitter.

           If the MTX-120 is accidentally subjected to spray or splash,
           immediately wipe it with a soft cloth.  If the unit is contam-
           inated with salt water, wipe it with a soft cloth moistened with
           fresh water.  Then, dry the radio.
