Muting Functions - Sony mb-806a Bedienungsanleitung

Muting Functions

This tuner has the following three muting functions,
which 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.
(2) Tone squelch
The audio output is obtained only when the tuner
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 tuner 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.
To turn off the muting functions
While holding down the GP and CH buttons, turn the
POWER switch to ON. All indications momentarily
appear, then go off. "OFF" is then displayed. This
procedure cancels all three muting functions at the
same time.
To turn on the muting functions
Turn the POWER switch to OFF, then to ON again.
The three muting functions are activated at the same
time.
