Check the Synchronous Cables

When no software is loaded, a faulty cable can be detected only by

substituting with a new cable:

1. Replace a section of synchronous cable with a new cable.

2. Attempt to load the software.

3. If loading is successful, you have solved the problem (the re-

placed cable is faulty).

If loading is unsuccessful, the cable you tested was not faulty.

Reconnect the cable.

Repeat the procedure until you have isolated the faulty cable.

If you still cannot solve the problem, contact Digital Services.
