erating instructions of the transmitter.

5) With the volume control (6) 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 (2) [keep the button pressed for 1 s as a
minimum]. The display shortly indicates

and then

extinguishes completely. 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

(5) pressed for 2 s. The display

shortly shows

and then returns to its pre-

vious indication. In the adjusting mode “FREQ.”,
FREQ. (f) keeps flashing.

Note: To exit the mode “FREQ.” without ad

justing the frequency, press the key . Then the
unit changes to the mode “SCAN”. In the mode
“SCAN”, press the key

once again. The dis-

play indicates

, then the unit returns to

normal operation.

2) Use the cursor keys (4) to adjust the frequency:

Each time the key

is pressed, the frequency is

increased by 125 kHz, each time the key

pressed, it is decreased by 125 kHz.

3) For memorizing the frequency, press the key

once again. The display shortly indicates

and

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

(5)

pressed for 2 s. Then press the key once again to
change into the mode “SCAN”. The display shortly
shows

and then returns to its previous indica-

tion. In the adjusting mode “SCAN”, SCAN (a)
keeps flashing.

Note: To exit the mode “SCAN” without starting
the frequency scanning, press the key

once

again. The display indicates

, then the

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

once

again. The display shortly indicates

and 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
