4.15 Error Information
The MO-180 can report two types of errors. One type is triggered by some
malfunction in the modulator's circuitry. The other type is related to problems
encountered in the normal operation of the modulator (e.g. TS or SFN synchronisation
problems).
The first 16 errors taking place during the operation of the modulator are
internally stored and can be retrieved or deleted by means of two functions in the
STATUS menu: Error List and Clear Errors.
This section describes the error list display format and the meaning of the codes
that appear in each case for each type of error.
Error types
The control program of the MO-180 can detect and display up to three types of
errors. Some of them correspond to modulator malfunction and must be directly dealt
with at a PROMAX's Customers Service Centre (CSC). Others flag up problems in the
normal operation of the modulator.
