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.
Before changing anything in the P
ULSAR remove the power cord to switch
off the power supply.
Persons working with the P
ULSAR should be grounded with a resistor iso-
lated wrist strap before touching the electronic components and before
removing any assembly from the unit.
