Adjusting the receiver channel
First turn on the transmitter (see section
"Where to place the transmitter").
As soon as the receiver is turned on, it au-
tomatically tunes itself to the first strong si-
gnal found (normally the transmitter
frequency). If, for some reason, the selec-
ted channel is not the correct one (e.g. be-
cause of interference or another nearby
system), press the TUNE button at the
rear of the receiver until you can hear the
audio signal loud and clear. If
you decide to change the transmitter
channel (see section "Changing the trans-
mission channel"), the frequency search
tuning must be re-started by pressing the
TUNE button on the receiver again.
