4.5 MAINTENANCE
DISASSEMBLY OF THE VIDEO AND AUDIO
CARDS.
For the removal of the RS232 cards and Power
Supplies, undo the tightening screws on the edge of
the panel and pull on the card.
For removal of the Power Supply block, withdraw
the adjacent panel to facilitate access.
Then disconnect the power cord and exchange the
Power Supply block.
For the extraction of the audio/video blocks (see
diagram of implantation of the matrix in beginning
of this manual), it is necessary to withdraw all
tightening screws of the input cards and the output
cards, because they are fitted to the same block.
The cards and blocks must be returned to the
factory for testing purposes. A visual examinationm
can be made by the user for the audio and video
connectors.
