6 Operation
Connect the power supply unit provided to the
power supply jack (11) and to a mains socket
(230 V~ / 50 Hz). After connection to the power sup-
ply, the receiver is switched on.
To switch the receiver on or off, use the button
POWER (2): Keep the button pressed for approx.
1 second.
If the receiver is not in use for a longer period of time,
disconnect the power supply unit from the mains
socket. Even when the receiver is switched off, the
power supply unit has a low power consumption.

7 Setting the Transmission Channel

To set the transmission channel, the receiver offers
3 operating modes. Use the buttons SET,
(5) to make the settings.
When setting the channel, make sure that any
switched-on transmitters of wireless systems oper-
ated at the same time are not too close to the
receiver (minimum distance: 1 m).

7.1 Selecting the operating mode

The display indicates the current operating mode:
"MANUAL", "SCAN" or "PRESET" (A). To select the
desired mode, use the button
button pressed for approx. 1 second to go to the
next mode (or keep the button pressed until the
mode is indicated, then release it).

7.2 Mode MANUAL

In the mode MANUAL, the desired radio frequency
can be selected manually from the 442 radio fre-
quencies available (
1) Use the button or
UAL ( chapter 7.1). The display will indicate
the most recent radio frequency (G) and corre-
sponding channel number (E) adjusted in the
mode MANUAL or SCAN.
2) To activate the setting mode, keep the button
SET pressed for approx. 1 second until the
channel indication (E) and the frequency indica-
tion (G) start flashing.
Note: When no button is pressed, the setting mode will
be exited after a few seconds.
3) Use the button
steps of 25 kHz). To run through the frequen-
cies, keep the corresponding button pressed.
4) The setting mode will be exited automatically
after a few seconds or when the button SET is
pressed.

7.3 Mode SCAN

In the mode SCAN, the receiver will automatically
find the next free channel. When multiple systems
are operated at the same time: Before performing
the channel scan, switch on the transmitters that
have already been set to a transmission channel.
Thus, all channels already being used or incompat-
ible with the channels already set will be skipped
during the channel scan. In this mode, depending
on local conditions, up to 12 channels can be oper-
ated at the same time without mutual interference.
1) Use the button
( chapter 7.1). The display will indicate the
most recent radio frequency (G) and correspond -
ing channel number (E) adjusted in the mode
MANUAL or SCAN.
2) To activate the setting mode, keep the button
and
SET pressed for approx. 1 second until the
channel indication (E) and the frequency indica-
tion (G) start flashing.
Note: When no button is pressed, the setting mode will
be exited after a few seconds.
3) To start the channel scan, press the button
(scan in ascending order) or
descending order). The scan will stop when the
next interference-free channel is reached. As
long as the setting mode is still activated, the
scan will always restart when the button is
pressed again.
4) The setting mode will be exited automatically
after a few seconds or when the button SET is
pressed.

7.4 Mode PRESET

In the mode PRESET, a channel can be selected
from one of 4 preset groups ("P1" ... "P4") [
—
, page 13]. Each group includes 8 intermodula-
tion-free channels, i. e. channels which may be
used at the same time without mutual interference.
Thus, this mode is suitable for operating multiple
systems at the same time. In case of interference
occurring at the place of operation, select a differ-
ent group or use the mode SCAN to set the chan-
nels for the systems.
1) Use the button
SET ( chapter 7.1). The display will indicate
the most recent radio frequency (G) and corre-
sponding channel number (E) adjusted in this
mode. The indication GP (B) will display the
group to which the frequency has been
assigned ("P1" ... "P4"); the indication CH (C)
will display the channel number of the frequency
within this group ("1" ... "8").
