Service

The KAM-XM modules make extensive use of surface-mount technology
and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be ser-
viced in the field unless as directed by Grass Valley Customer Service.

Power-up Diagnostics Failure

If the module has not passed self-diagnostics, do not attempt to trouble-
shoot. Return the unit to Grass Valley (see

Module Repair

).

Troubleshooting

If your module is not operating correctly, proceed as follows:

If module power is not present, check fuse F1 (see

Figure 44

).

Check for presence and quality of input signals.

Verify that source equipment is operating correctly.

Check cable connections.
