The 8900FSS and its host module 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.
If your module is not operating correctly, proceed as follows:
■ Check frame and module power and signal present LEDs.
■ Check for presence and quality of main input and reference signals.
■ Verify that source equipment is operating correctly.
■ Check cable connections.
■ Check output connections for correct I/O mapping (correct input con-
nector is used for the corresponding channel output).
If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.
