Sony WRT-808A Operating Instructions Manual page 11

Use of RF power output switch
The RF power output switch (located inside of the battery
compartment) selects the RF power output either 50 mW or
10 mW. In normal use, set the switch to "50" (factory preset
position).
50 mW output is suitable for optimum transmission over
long working distance.
10 mW output will be suitable for multi-channel operation
to eliminate the interference.
Use of input LEVEL control
When the AF/PEAK indicator lights in green continuously,
the supplied audio signal is continuously over the reference
level. If this occurs, use the input LEVEL control to avoid
sound distortion.
By turning the control to "–10", the WRT-808A provides 50
dB input attenuation and can be inputted +4 dB (maximum
20 dB) line level signal.
Notes on microphone system operation
•
To operate with two or more channels, maintain a distance
of at least 30 cm (one ft.) between each pair of
transmitters.
For details of operation with two or more channels, refer
to the Operating Instructions for the WRR-800A/801A/
805A, etc.
•
Ensure that the transmitter set to channels not being used
are either turned off or set to the minimum output level.
•
When powering the transmitter on or off, to keep the noise
to a minimum, set the audio output level from the tuner or
mixer to a minimum.
•
Powering the transmitter on without checking the channel
selection first may interfere with the operation of other
microphones/transmitters, if the current setting is already
being used.
•
To prevent noise generation, keep the transmitters at least
3m (10 feet) away from the tuner antennas when the
system is operated using a group which allows selection of
up to 11 channels.
•
Do not grip the transmitter while using as it
will significantly degrade good
performance, causing dropouts, etc. Hold
the microphone itself as shown.
