operations in Setting mode.
The next time you turn on the transmitter (by setting
the POWER switch to ON), the transmitter will enter
Transmitting mode with the selected channel number
(or frequency).
Notes
• The transmitter cannot transmit in Setting mode.
• Make sure that the channel selected on the
transmitter is the same as that selected on the tuner
being used in the same system.
• Depending on the noise or interference conditions,
all selectable channels may not be usable. If
necessary, you can determine which channels are
usable by cycling the channel selection through a
number of channels on the tuner with the unit set to
OFF. Those channels for which the RF indicator on
the tuner does not light are usable.
• If there is a TV broadcasting station near by, do not
use the station’s channel.
• The transmitter may not operate correctly if it is
turned on immediately after being turned off in
Setting mode. Wait for a few seconds before turning
the power on again.
• The channel numbers and frequencies of your
transmitter are shown on the “Sony Wireless
Microphone System Frequency List” supplied with
the manual.
Resetting the Accumulated
Time Indication
The time indication accumulates time in hours and
minutes when the WRT-8B is on.
Reset the indication to “00:00” whenever you replace
the batteries so that it can display the running time of
the batteries.
1
Set the transmitter to Setting mode.
2
Press the SET button until the accumulated time
indication appears on the display.
3
Press the – button.
The time indication resets to “00:00.”
While you see “00:00” indication, you can go back
to previous value by pressing the + button.

mode. Or, press the SET button to continue
operations in Setting mode.
Changing the RF Output
Power
You can select the RF output power from the levels of
H (50mW) and L (10 mW) in Setting mode. Set the
RF output power to L (10 mW) for simultaneous
operation of multiple channels, and set it to H (50
mW) for long-distance operation.
1
Set the transmitter to Setting mode.
2
Press the SET button until the RF output power
indication appears on the display.

power.
Adjusting the Audio Input
Level
You can change the audio input level in a range of –
60 dBV to –20 dBV (when the MIC/LINE selector is
at MIC position) or –20 dBu to +20 dBu (when the
MIC/LINE selector is at LINE position).
1
Set the MIC/LINE select switch according to the
equipment connected to the audio input connector.
When a microphone is connected to this unit, set
the selector to MIC position; when a mixer, etc., is
connected, set it to LINE position.

WRU-806/8N also starts flashing.
Note
The indication may be incorrect if the batteries are not
new when installed. If you plan to use the transmitter
for a long period, it is best to replace the batteries with
new ones.
Notes on batteries
• Use new alkaline batteries.
• Do not pair different types of battery.
• Always replace the two batteries together.
• The batteries are not rechargeable.
• Be careful to install the batteries with the correct
polarity.
• When not using the transmitter for a long period,
remove the batteries to avoid leakage. If the
batteries do leak, clean all leakage from the battery
holder case and the unit. Leakage left in the holder
case and the unit may cause poor battery contact. If
there seems to be poor battery contact, consult your
Sony dealer.
