Removing the Genlock Board For RS-422 Board Removal

removed to allow a firm grasp of the RS-422 board.
To remove the Genlock board from slot J16 for RS-422 board removal:
1. Remove all external and internal cables from the Genlock board. Be sure to
make a cabling diagram that you can use later to reinstall the cables.
2. Use the Torx tool with the T15 tip to remove the screws which secure the
Genlock board to the rear panel (see
Ê and Ë in Figure 5 as an example).
3. Use the extraction lever on the front of the board and the extraction ring at
the back of the board to lift the circuit board free of the connectors on the
motherboard.
4. Carefully remove the RS-422 Interface board by grasping the edge of the
circuit board above the motherboard connector and pulling up.
