RECEIVE AND TRANSMIT

■ Functions for receive

D D Squelch function
The squelch function detects signals with voice com-
ponents and squelches (mutes) unwanted signals
such as unmodulated beat signals. This provides
quiet stand-by.
When you need to receive weak signals, the squelch
should be turned OFF.
➥ Push [MUTE] several times to select a mute type.
Available types are voice mute, signal level mute
(level 1—100), call mute or mute OFF.
• When select the mute type, transceiver emits different
confirmation beep for each type.
OFF—1 long beep,
Call mute—1 short beep,
Signal level mute—2 short beeps,
Voice mute—3 short beeps
D D RF gain setting
The receiver gain can be reduced with the RF gain
setting. This may help to remove undesired weak sig-
nals while monitoring strong signals.
Usually, the AGC function reduces the RF gain ac-
cording to the receive signal strength and these weak
signals are removed. However, during no signal re-
ception, these weak signals may not be heard.
In such cases, the RF gain may be useful for setting a
minimum level at which to hear signals.
