Switching the unit on and off
Do not switch the multiplexer on until the system has
been set up as desired and you have checked for
loose connections and correct polarity.
Before operating the multiplexer, ensure that the
technician responsible has installed and programmed
the unit correctly and that all functions are in full work-
ing order.
Note
The installer will normally carry out all the
required machine programming operations
before initial start-up. Further multiplexer
installation and programming instructions are
provided elsewhere in this manual.
• Press the POWER switch to activate the multiple-
xer. The green indicator will now light up.
• Press the POWER switch to shut down the multi-
plexer, and the indicator light will go out.

Control buttons and screen display
All multiplexer control buttons are of the light-up type.
Illuminated camera buttons indicate which cameras
are currently selected, while function buttons light up
to show which functions are currently active.
The alarm button lights up red in the event of an
alarm.
Two monitors can be connected directly to the multi-
plexer. Depending on how the system is programmed,
digital functions – such as zoom or freeze-frame –
may only be available on one of the monitors. Both
monitors display various items of superimposed infor-
mation in text form, including – for example – date,
time, details of camera from where current image is
being transmitted, or activated alarms.
Note
Certain texts are not permanently displayed,
require activation by pressing the corre-
sponding button and only appear on the
main monitor (see page 14).
