(14) TX MON
This menu is to set Talkback Monitoring Volume for voice message
sent.
Be sure that power supply, microphone and antenna are
11
connected to the proper connectors before going to the next
step.
Turn the radio on by tuning VOLUME control clockwise.
21
Rotate the VOLUME knob to set a comfortable listening level.
31
SET the MODE switch to the desired mode.
41
Set the CHANNEL selector switch to select the desired channel.
51
Set the RF gain control full clockwise to maximum RF gain.

Listen to the background noise from the speaker. Turn the
71
SQUELCH control clockwise slowly until the noise disappears (no
signal should be present). Leave the control at this setting. The
Squelch is now properly adjusted. The receiver will remain quiet
until a signal is actually received. Do not advance the control too
far, or some of the weaker signals can not be heard.
