3) Speak/sing into the wireless microphone. The
volume of the audio signal received is shown on the
display via the indication AF (d): the more seg-
ments are displayed, the higher is the volume level.
Adjust the optimum volume on the transmitter
(→ see instruction manual of the transmitter).
Match the output level of the receiving unit to the
input of the subsequent unit with the volume control
(5).
4) With the squelch control (12) – CH. 1 for receiving
unit 1, CH. 2 for receiving unit 2 – adjust the thresh -
old value for the response of the squelch. The fur -
ther the control is turned clockwise, the higher is
the threshold value.
The squelch will mute the receiving unit if during
music intervals high-frequency interference signals
are received of which the level is below the thresh -
old value adjusted. With a higher threshold value,
however, the operating range of the wireless
system will be reduced as the receiving unit will
also be muted if the power of the radio signal of the
microphone falls below the threshold value adjust -
ed. Thus, a higher threshold value may be adjusted
with the squelch control if the reception of the
microphone signal is good. However, with a longer
distance between the transmitter and receiver, a
lower value should be selected.
5) After operation, switch off the receiver with the
switch POWER (3). If the receiver is not used for a
longer period, disconnect the power supply unit
from the mains supply as it will have a low current
consumption even with the receiver switched off.

receiving unit 2).
2) As long as the indication keeps flashing, the channel
may be selected: With the key

3) Approx. 3 seconds after the last actuation of a key,
the indication RX1 or RX2 will disappear and the
channel adjusting mode is exited.
Note: It is not possible to set both receiving units to the
same channel. The channel selected for one receiving
unit will be automatically skipped during channel
adjustment for the other receiving unit.
6.1.1 Lock mode
(locking the channel selector keys)
To prevent accidental change of the transmission
channels selected, it is possible to activate the lock
mode. With the lock mode activated, it is not possible
to call the channel adjusting mode for any of the two
receiving units.
1) To activate the lock mode, in one of the operating
panels, keep the keys
same time until LOCK (a) is displayed.
2) To deactivate the lock mode, in one of the operating
panels, press the keys
until LOCK disappears.
Note: The lock mode is automatically deactivated each
time the unit is switched on.
