Notes
•
Do not remove the batteries during group and wireless
channel selection. If they are inadvertently removed, re-
insert them immediately and repeat the steps on pages 12
to 13 from the beginning.
•
Make sure that the channel selected is the same as that
selected on the transmitter used in the same system.
•
Depending on the noise or interference conditions, the
selectable channels may not necessarily all be usable. If
necessary, you can determine the usable channels by
stepping the channel selection through a number of
channels on the tuner with the microphone/transmitter set
to OFF. Those channels on which the RF indicator of the
tuner does not light are usable.
•
If there is a TV broadcasting station near by, do not use
the station's channel.
•
The unit may not operate correctly if it is turned on again
immediately after turning off the power while in setting
mode. Pause for a few seconds or more before turning on
the power again.
•
When operating two or more UHF wireless microphone
systems using channels in different groups, ensure that the
systems are at least 100m (330 feet) apart from each other.
(The same applies also when using channels in a group if
the different UHF wireless microphone systems are
installed where they are within sight of each other.)

Connections
Caution
When connecting the unit to a camcorder, be sure to turn the
unit off.
Connect the OUTPUT (BAL) connector to the microphone
input connector on DSR-200, DCR VX-1000 or other
camcorders by using the supplied cable.
To secure the output cable connection, be sure to turn and
lock the connector cover as illustrated below.
For attaching the unit to a camcorder, see "Usae of the Soft
Case" on page 17.
To monitor audio output, connect the headphones to the
MONITOR connector. The monitoring level can be adjusted
by turning the MONITOR control.
Resetting the Accumulated Time Indication
The time indication accumulates time in hours and minutes
when the WRR-805A 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
Press the MODE button until the accumulated time
appears on the display.

Press the SET button.

Muting Functions
When the MUTING switch is set to ON, the following
muting functions 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 (15dBµ).
(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.
