3 INSTALLATION
Please read this chapter carefully before installing the option.
The installation procedure is only necessary when ordering this option sepa-
rately. When ordering a P
ULSAR
with Audio/Video Auxiliary Input, the installa-
tion has already been carried out during production.
This option cannot be installed together with the AUDIO/VIDEO AUX INPUT. If this option has been
installed, you can switch between two clear signals. With the option MAIN SCRAMBLED / AUX UN-
SCRAMBLED SUBSTITUTION, it is possible to switch between a scrambled signal or an unscram-
bled signal. However, it is not possible to work with two scrambled signals.
For the location of the boards, connectors and jumpers use the internal layout diagram.
