assembly.

If the part number is lower than 671-4945-02, the board will not
work with the Emergency Bypass option. Do not remove or replace
the cable. Contact Grass Valley Customer Service for an upgrade.

Power off the 2-M/E Main panel.

Remove the old ribbon cable from the lid (
Figure 5
).
3.
Attach the two closely spaced connectors on the new cable to the same
two boards in the lid (
Figure 6

cable must face down toward the hinge of the lid, to match the pin 1 and
2 side of the connector. These connectors are keyed for this orientation.
