6 Operation
After all connections have been made, switch on the
switch-over unit with the POWER switch (5). The
channel display (1) lights up, and the operating mode
AUTO is activated.
If the surveillance system will not be used for a
longer period of time, disconnect the power supply unit
from the mains socket as it continuously has a low
power consumption (even with the switch-over unit
switched off).
6.1 Manual camera selection
For manual selection of a camera picture press the
button (11) on the remote control corresponding to the
camera connection. The channel display switches to
the number of the selected channel, and the picture of
this camera appears on the connected monitor.
6.2 Operating mode AUTO
In case of the operating mode AUTO all camera pic-
tures are switched in a cyclical sequence. The chan-
nels where no video signal is present are automatically
skipped. This operating mode is switched on with the
AUTO button (8) on the remote control.
6.3 Operating mode SCAN
In the operating mode SCAN camera channels which
have been selected before are switched in a cyclical
sequence. After switching-on, these are the channels
CH1 to CH4 (factory setting). This order can be chang-
ed as follows:
1) Press the PRGM button (10):
the channel display (1) shows "P".
2) Press the SCAN button (7):
the channel display shows "c".
3) Via the buttons "1", "2", "3", and "4" (6) enter the
desired order (max. 4 steps).
4) Press the PRGM button (10):
the channel display (1) shows "-" and changes
to the present channel number again after approx.
3 s.
5) If another operating mode was selected before,
press the SCAN button (7) to have the programmed
sequence running.
Note: A programmed sequence is not stored when
switching off the switch-over unit. After switching on
again, the factory setting (1, 2, 3, 4) is adjusted as
before.
6.4 Adjustment of the dwell time
The dwell time, i. e. the time until the next sequential
switching, is preset to 10 s after switching on. It can be
changed as follows:
1) Press the PRGM button (10):
the channel display (1) shows "P".
2) Press the DWELL button (9):
the channel display shows "d".
3) Via the numerical keys (6) enter the desired time
(1 – 99 s). When entering "0", a time of approx.
0.5 s is adjusted.
4) Press the PRGM button (10):
the channel display shows "-" and changes to
the present channel number after approx. 3 s.
Note: A changed dwell time is not stored when switch-
ing off the switch-over unit. After switching on again,
the time is 10 s as before.
