5.1 Operation of the receiver module
Each receiver unit (A and B) provides a control (2)
to adjust the volume and to switch it on and off .
The display (1) is divided into two parts: left half
for receiver unit A, right half for receiver unit B .
When a receiver unit has been switched on, the
display will indicate the transmission channel . To
briefly indicate the radio frequency, press the
button  (for unit A) or  (for unit B) .
5.1.1 Setting the transmission channels
Use the controls (2) to switch on the receiver
units . Do not switch on the corresponding trans-
mitter for the time being .
Channel scan
Keep the buttons  and  (3) simultaneously
pressed for approx . 1 second until
on the display . The scan will start: The receiver
units will be set to free channels without mutual
interference . If no free channels are found, the
channels set will be kept .

Manual channel selection
If both receiver units A and B are switched on:
1) Keep the button SET (3) pressed until the
channel indication for receiver unit A starts
flashing on the display .
2) Select the channel for receiver unit A with
the button  or  and then confirm with
the button SET .
3) The channel indication for receiver unit B
starts flashing on the display . Select the chan-
nel for receiver unit B with the button  or
 and then confirm with the button SET .
If only one receiver unit A or B is switched on:
Keep the button SET pressed until the channel
indication starts flashing on the display . Select
the channel with the button  or  and then
confirm with the button SET .
Notes:
1 . The receiver units cannot be set to the same channel .
2 . If a channel is not confirmed within 10 seconds with
the button SET, the setting mode will be exited and
the channel previously set will be kept .
3 . If, with the transmitter switched off, the respec-
tive segment bar A or B on the display indicates
reception, interference signals or signals from other
transmitters are being received . In this case, select a
different channel .
5.1.2 Adjusting the volume
Switch the transmitters on and set them to the
channel of receiver unit A and receiver unit B
respectively . The respective segment bars on
the display will then indicate the strength of the
radio signals received . Use the controls (2) to
adjust the desired volume for each receiver unit .
5.1.3 Setting the squelch
The squelch function will mute the respective
receiver unit when the level of the radio signal
falls below the threshold value adjusted . Thus,
interference signals will not cause noise when
the transmitter is switched off or when its radio
signal is insufficient: If the levels of the interfer-
ence signals are below the threshold value, the
receiver unit will be muted . A high threshold
value offers high interference resistance, but it
will also reduce the transmission range .
1) Switch off the receiver units A and B . Then
keep the button SET (3) pressed while switch-
ing on a receiver unit . The display will indicate
or , with the number flashing .
