5.1.2 Volume attenuation during
microphone announcements
During microphone announcements, the volume
of the MP3 / CD player and of the audio unit con-
nected to the jack LINE IN (24) can be attenuated
automatically . This will make it easier to under-
stand announcements .
1) Use the switch MUSIC RETURN TIME (28) to
attenuate the volume:
LONG After an announcement, the attenua-
tion will be deactivated with a delay .
OFF no attenuation
SHORT After an announcement, the attenua-
tion will be deactivated immediately .
2) Use the control DEPTH (29) to adjust the level
of attenuation . When the control is set to the
left stop, the volume will not be attenuated .
When the volume is attenuated during an an-
nouncement, the green LED on the left of the
control will light up .

5.2 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) .
5.2.1 Setting the transmission channels
Use the controls (2) to switch on the receiver
units . Do not switch on the corresponding wire-
less microphones / transmitters 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 chan-
nel indication for receiver unit A starts flashing
on the display .
2) Select the channel for receiver unit A with the
