Selecting And Cancelling The T (Tone Squelch) Off Mode - Sony WRR-855S Mode D'emploi

Example: When the channel group
00 is selected for U62 model
6
When the desired channel number is
displayed, leave the tuner unit for
about five seconds until the selected
channel number indication stops
flashing and the selection is stored in
memory.
Interference-check function
Before operating a wireless microphone or
transmitter, you can check for possible
interference by using the interference-
check function of this tuner unit.
To check the interference, simultaneously
press the + and – buttons in the channel
selection mode (while the channel number
indication flashes). The channels of the
selected group are automatically switched
one by one in sequence (this operation is
called "scanning").
Notes
• When the SQUELCH switch is set to ON
and the tuner unit is not in the T OFF
mode (see page 13), scanning stops and
the channel at that time is selected if a
tone signal (32.768 kHz) is detected in
the signal received during scanning.
However, scanning will not stop if a
interfering signal having no tone signal is
received. In this case, check for the
interference by observing the RF input
level indicator or the RF (radio
frequency) input level indications in the
display.
• Scanning is automatically cancelled
when all the channels of the selected
group are scanned twice. To cancel
scanning in progress, press any of the
operation buttons.
• If an extremely strong signal is received,
scanning may stop at a point other than
the actual channel.
Selecting and Cancelling
the T (Tone Squelch) OFF
Mode
The WRR-855S has the following three
squelch functions, which work in
combination.
(1) Squelch 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 is turned off when the RF input level
falls below the selected level.
(2) Tone squelch
The audio output is obtained as long as the
tuner unit receives an RF signal which
includes a specified tone signal.
(3) Noise squelch
The audio output is turned off to eliminate
noise which may be heard when there is
such excessive interference RF signal that
the tone squelch does not work.
Only the tone squelch function described in
(2) above can be canceled by selecting the T
(tone squelch) OFF mode. Apply this mode
