further clockwise; otherwise, the microphone
signal may also be suppressed .
4) Switch on the microphone . For this purpose set
the switch (13) to the upper position . In mid-
position the microphone is set to mute, i . e . it is
switched on but no audio signal is transmitted .
At the receiver, the receiving LED RF must light
up . If it remains dark, the reception is too poor:
a Is the battery in the microphone exhausted?
( ☞ chapter 4 .1)
b Is the distance between microphone and re-
ceiver too long? The range is approx . 30 m .
c Is the reception disturbed, e . g . by metal
objects in the transmission path?
d Can the reception be improved by turning the
receiving antennas?
e Is the muting threshold adjusted with the con-
trol SQ 1 (10) too high? (
5) From a certain microphone volume the yellow
LED AF (2) lights up . The LED is independent of
the position of the control VOLUME (1) .
If the microphone is overloaded because
the volume at the microphone is too high, the
volume of the sound source must be attenuated
or the microphone distance to the sound source
must be increased .
If the volume at the microphone is too
low, a poor S / N ratio is obtained . The volume
of the sound source must be increased or the
microphone distance to the sound source must
be reduced .
6) Adapt the output volume of the receiver with
the control VOLUME (1) to the input of the
following audio unit .
7) After operation, switch off the receiver with
the switch
microphones; otherwise, the batteries will be
ex hausted the next time the system is used .
If the microphone system is not used for
a longer period, disconnect the plug-in power
supply unit from the socket; otherwise, the
system will have a low power consumption even
if the receiver has been switched off .
