30 Troubleshooting
Meanings
The software version of the
transmitter is not suitable for use
with this receiver.
The RF indicator lights up even
when the transmitter is turned off.
Two or more transmitters are set
to the same channel.
The channel is not set within the
same channel group.
Remedy
Refer to the transmitter software
compatibility table, and confirm
whether the software version of the
transmitter is suitable for use with
this receiver (see page 32). If it is
not suitable, software update is
necessary. Contact your Sony
service representative.
Jamming radio waves are being
received. Set the channel whose
RF indicator on the receiver does
not light up, and then set that same
channel on the transmitter. When
two or more transmitters are being
used, change to another channel
group that is unaffected by jamming
radio waves. When doing this, the
clear channel scan function is
useful.
It is not possible to use two or more
transmitters that are set to the same
channel. Refer to the Sony digital
wireless frequency lists and reset
the transmitter channel.
The channel plan of the receiver
use 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.
