Notes on using with a WD-820A
• This unit does not supply the internal booster of the
optional AN-820A UHF Antenna through the ANTENNA
A,B connectors. It is impossible to connect the AN-820A
directly.
• When adding the WRR-802A by cascade connection to a
tuner system containing the WD-820A UHF Antenna
Divider, use a coaxial cable (5D-2V, RG-212/U or
equivalent) with length of 30 m (100 feet) as shown in the
figure.
• To avoid noise, remove the transmitter from the antennas
as far as possible when setting the channel or waiting with
the transmitter powered.
Notes
• Do not simultaneously use two or more microphones and
transmitters that are set to the same channel.
• Separate the reception antennas and the transmitter by
more than 3 m (9 feet 11 inches).
• The number of wireless microphone channels actually
usable in a multi-channel system may be smaller than the
normal capacity of that system if there is interference from
TV broadcasting or other RF signals.
• When operating two or more UHF wireless microphone
systems using the same wireless channel in the same
group, ensure that the systems are at least 100 m (330
feet)

Apart from the normal indications, the following error
messages may appear on the display.
Meaning Remedy
Err 01
Message
An error has occurred in
the backup memory data. The memory data is initialized. Reset the
group and channel
settings.
Contact your nearest
Sony dealer.
The PLL-synthesized
circuit has a malfunction.
Err 02
NO TONE As no tone signal is
available or a tone signal
other than 32.768 kHz is
being received, the audio
signal output is muted.
Make sure that the
transmitter is turned on.
If it is, then the problem
lies in the transmitter’s
tone signal generator or
the tuner’s tone squelch
circuit. Contact your
nearest Sony dealer.
If you are using a WRT-
810A wireless
microphone, a “NO
TONE” message
appears when you turn
off the AF switch, but
this is normal.
Error Messages
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.
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.

Note on Adjustment
The RF level of the input signal (the output level of the
signal generator) for adjustment is expressed as an open
ended voltage in unit dBu(0 dBu= 1 uV).
The adjustment is to be performed by calibrating the output
level of the signal generator as shown below.
Calibration method
(1) Connect the RF millivoltmeter to the signal generator
as shown in the figure below.
(2) Adjust the level of the output signal from the signal
generator (SSG) so that the RF millivolt meter reads
50 mV. The level of the output signal from the signal
generator (SSG) when RF millivoltmeter reads 50 mV
shall be specified as 100 dBu(at no load).
