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.
