Run a Tuner Diagnostic

This command enables you to run a diagnostic test on all OAT100R tuners.

Caution: The tuner diagnostic requires that all tuners be switched to a known good channel for testing purposes. Thus, standard system operation will be disrupted for the duration of the routine (up to five minutes).

Caution: If there is not a known good channel that is appropriate for each of the tuners, note in advance that the tuner(s) for which the channel is not valid will fail the diagnostic.

1.At the Setup Command > prompt, type tundiag and press Enter.

2.At the Enter channel [2] > prompt, either press Enter to accept the default value in brackets, or type in the number of a known good channel to test and press Enter.

The system will prompt for confirmation:

This is a diagnostic routine that may only be run in a controlled environment such as the factory.

Are you sure you want to continue (y/n)? [y/n]:

3.Either:

Type y and press Enter to initiate the diagnostic routine. When testing is complete, the system will display a results screen (see example below).

Type n and press Enter to return to the Setup Menu command without running the tuner diagnostic.
