driver is provided. The limiter will limit the vol-
ume to a maximum value depending on the
position of the control VOL. This will allow a
higher monitoring volume for low and average
signal levels. However, if you wish to maintain
the dynamic power of the music signal, deacti-
vate the limiter (OFF).
7) When a microphone or an audio unit is con-
nected to the jack LINE / MIC (18), set the signal
gain with the control LINE / MIC GAIN (17) so
that the signal for the earphones is neither dis-
torted nor too low in volume. For this purpose,
use the screwdriver provided.
8) When all settings have been made on the
receiver, use the clip (19) to attach it to your
clothes (e. g. belt or waistband).
9) If the transmission results are poor, increase the
transmission power of the transmitter: Use the
screwdriver provided to engage the button TX
BOOSTER (10).
However, this may result in interference with
other wireless systems in the vicinity. In this
case, disengage the button.

) To save the batteries, switch off the receiver
after operation and during longer intervals. Turn
the control VOL to the left stop until it locks.
To switch off the transmitter, briefly keep the
button
pressed until the channel display is
extinguished. If the transmitter is not in use for a
longer period of time, disconnect the power sup-
ply unit of the transmitter from the mains socket.
Even when the transmitter is switched off, the
power supply unit has a low power consump-
tion.

CAUTION Never adjust a very high volume.
Permanent high volumes may
damage your hearing! Your ear
will get accustomed to high vol-
umes which do not seem to be
that high after some time. There-
fore, do not further increase a
high volume after getting used
to it.
