1) Body-pack transmitter (UTX-B03) / hand-held microphone (UTX-M03) / plug-on transmitter (UTX-P03) only
2) Body-pack transmitter (UTX-B03) / plug-on transmitter (UTX-P03) only
3) Portable diversity tuner (URX-P03) only
Solution
Use the same channel setting on both the
transmitter and tuner.
Two or more transmitters cannot be used on the
same channel. Refer to the frequency list stored
on the supplied CD-ROM, and reconfigure the
channel on each transmitter.
The channel plan is set so that no signal
interference occurs when two or more transmitters
are used simultaneously. Set each transmitter to a
different channel within the same channel group.
Use the channels separated by at least two
channels (250 kHz).
Set the channel on the tuner to a channel for which
the RF indicator does not light, or use the Clear
Channel Scan function to switch to a channel
without interference. Then, set the transmitter to
the same channel as the tuner.
If using two or more transmitters, change to a
channel group that is not affected.
Reduce the distance between the infrared receptor
on the transmitter and the infrared transmission
port on the tuner to within about 20 cm (8 in.).
The transmitting distance is reduced when
interference from strong sunlight, for example, is
present. Place the transmitter and tuner as close
to each other as possible.
