When operating two or more UHF wireless microphone
systems using channels in different groups, ensure that the
systems are at least 100 m (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.)

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 7 to
9 from the beginning.
•
Make sure that the channel selected is the same as that
selected on the transmitter used in the same system.
•
Be sure to set tuners 1 and 2 to different channels.
•
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 the unit with one transmitter (for
example, using tuner 1 for reception, and leaving tuner 2
unused), noise or audio signals may occur on the unused
tuner, if the tuner and the transmitter are too close to each

Squelch functions
When the SQUELCH switch is set to ON, the following functions
work in combination.
(1) Squelching 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
squelched when the RF input level falls below the squelch level
selected
.
(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
squelched 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 squelched to eliminate noise which may be
heard when there is such excessive interference RF signal that the
tone squelch does not work.
Accumulated time of
battery use
Resetting the Accumulated Time Indication
The time indication accumulates time in hours and minutes
