Mobile whip antennas utilize the metal body of the
vehicle as a ground plane. When mounted at a corner of
the vehicle they are slightly directional, in the direction of
the body of the vehicle. For all practical purpose, however,
the radiation pattern is nondirectional. The slight
directional characteristic will be observed only at extreme
distances. A standard antenna connector (type So-239) is
provided on the transceiver for easy connection to a
standard PL-259 cable termination.
If the transceiver is not mounted on a meta' surface, it is
necessary to run a separate ground wire from the unit to
good metal electrical ground in the vehicle. When installed
in a boat, the transceiver will not operate at maximum
efficiency without a ground plate, unless the vessel has a
steel hull.

Before installing the transceiver in a boat, consult your
dealer for information regarding an adequate grounding
system and prevention of electrolysis between fittings in
the hull and water.

EXTERNAL SPEAKER
The external speaker jack (EXT SP.) on the rear panel is
used for remote receiver monitoring. The external speaker
should have 8 ohms impedance and be able to handle at
least
4
watts. When the external speaker is plugged in, the
internal speaker is disconnected.
PUBLIC ADDRESS
To use the transceiver as a public address system,
connect an external 8 Ohms speaker
(4
watts minimum)
to the PA SP jack located on the rear panel. Direct speaker
aay from the microphone to prevent acoustic feedback.
Physical separation or isolation of the microphone and
speaker is important when operating the PA at high output
level.

: Turn clockwise to
apply power to the radio and to set the desired
listening level.
3.
SQUELCH CONTROL : This switch is used to
eliminate background noise being heard through the
receiver which can be disturbing when no signal is
being received. To use this feature of your radio, gently
turn the switch fully counterclockwise and then turn
clockwise until the background noise is just eliminated.
Further clockwise rotation will increase the threshold
level so that only strong signals will be heard.

MIC GAIN CONTROL
: Adjust the microphone gain
in the transmit and PA modes. This controls the gain to
the extent that full talk power is available several
inches away from the microphone. In the Public
