Muting Functions

When the MUTING switch is set to ON, the following
muting functions work in combination.
(1) Muting by RF input level
As sufficient S/N for the audio output may not be obtained if
no RF signal is received or the RF input level is low. The
audio output can be muted when the RF input level falls
below the muting level (15dBµ).
(2) Tone squelch
The audio output is obtained only when the unit receives an
RF signal which includes a specified tone signal. The audio
output is muted to eliminate noise which may be heard when
the transmitter is turned on/off or the unit receives an
interference RF signal.
(3) Noise squelch
The audio output is muted to eliminate noise which may be
heard when there is such excessive interference RF signal
that the tone squelch does not work.
