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 chan-
nel indication (E) and the frequency indication
(G) start flashing .

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

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 dif-
ferent group or use the mode SCAN to set the
channels for the systems .
1) Use the button
PRESET (
cate the most recent radio frequency (G) and
corresponding 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") .
