and potential sources of interference, such as
e. g. motors or fluorescent tubes.
d the reception can be improved by turning the
antennas.
Note: If the power of the radio signal falls below a
defined threshold value, the receiver will be muted.
This will prevent noise on the receiver in case of
reception interference or when switching off the
transmitter. Then the display indicates MUTE (h).
The muting is deactivated as soon as the unit re-
ceives a radio signal of sufficient power again.
3) Switch on the subsequent audio unit or advance
the corresponding fader on the mixer.
4) Speak/sing into the microphone. The volume level
of the audio signal received is shown via the bar
graph AF (b) and the indication PEAK (e):
The more segments of the indication AF are in-
serted, the higher the volume level. The indication
PEAK should only light up shortly with signal
peaks. If it lights up permanently, the level is too
high and distortions will occur.
Adjust the optimum volume on the transmitter by
means of the indications AF and PEAK → see op-
erating instructions of the transmitter.
5) With the volume control (1) adapt the output level of
the receiver to the input of the subsequent unit.
6) The receiver may be locked to prevent accidental
change of frequency or accidental switching off
→ see chapter 5.2.
7) After operation switch off the receiver with the
switch POWER (5) [keep the button pressed for 1 s
as a minimum].
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 when the receiver is switched off.

5.1 Adjusting the reception frequency

The reception frequency can either be adjusted
manually or via the automatic frequency scanning.
5.1.1 Mode "FREQ.":
manual frequency adjustment
1) Keep the key SET (3) pressed for 2 s. The display
shortly indicates
vious indication. In the adjusting mode "FREQ.",
FREQ. (f) keeps flashing.
Note: To exit the mode "FREQ." without adjusting
the frequency, press the key SET. Then the unit
changes to the mode "SCAN". In the mode
"SCAN", press the key SET once again. The dis-
play indicates
normal operation.
2) Use the cursor keys (4) to adjust the frequency:
Each time the key
increased by 125 kHz, each time the key
pressed, it is decreased by 125 kHz.
3) For memorizing the frequency, press the key SET
once again. The display shortly indicates
the unit returns to normal operation.

5.1.2 Mode "SCAN":
automatic frequency scanning
The mode "SCAN" can only be recalled if the unit is in
the mode "FREQ." and if the cursor keys (4) have not
been pressed in this mode.
1) The transmitter must be switched on and be ad-
justed to the desired transmitting frequency → see
operating instructions of the transmitter.
2) To go to the mode "FREQ.", keep the key SET (3)
pressed for 2 s. Then press the key once again to
change into the mode "SCAN". The display shortly
indicates
cation. In the adjusting mode "SCAN", SCAN (a)
keeps flashing.
Note: To exit the mode "SCAN" without starting
the frequency scanning, press the key SET once
again. The display indicates
unit returns to normal operation.
3) Start the frequency scanning with one of the cursor
keys (4):
If the transmitter frequency is higher than the
frequency currently adjusted on the receiver, press
the key . Then the frequencies are scanned in
ascending order.
If the transmitter frequency is lower than the fre-
quency currently adjusted on the receiver, press
the key . Then the frequencies are scanned in
descending order.
When the frequency adjusted on the transmitter
is found, the scanning will stop.
4) To memorize the frequency, press the key SET
once again. The display shortly indicates
the unit returns to normal operation.

5.2 Lock function

With the lock function activated it is no longer possible
to switch off the receiver and to recall the modes for
frequency adjustment. If this is tried, the display
shortly indicates

To activate the lock function, keep the key
pressed until the display indicates
releasing the key it returns to its previous indica-
tion, the receiver is locked.
To deactivate the lock function, keep the key
pressed until the display indicates
releasing the key it returns to its previous indica-
tion, the locking is deactivated.
