Muting Functions; Channel Setting - Sony WRR-800A Mode D'emploi

Muting Functions

This unit 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 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.

Channel Setting

Take the following precautions to prevent interference and
noise.
• Do not simultaneously use two or more microphones and
transmitters that are set to the same channel.
• When simultaneously using two or more tuners, always set
the tuners to different channels within the same group
(other than group 00).
• Separate the reception antennas and the transmitter by
more than 3 meters (9 feet 11 inches).
