Performance Check Interval
Generally, the performance check described in section 4, Performance Verifica-
tion, should be done every 12 months. In addition, a performance check is
recommended after module replacement.
If the MPEG generator does not meet performance criteria, repair is necessary.
Strategy for Servicing
Throughout this manual, the term “module” refers to any field-replaceable
component, assembly, or part of the MPEG generator.
This manual contains all the information needed for periodic maintenance of the
MPEG generator (Examples of such information are procedures for checking
performance).
Further, it contains all information for corrective maintenance down to the
module level. To isolate a failure to a module, use the fault isolation procedures
found in Troubleshooting, part of section 6, Maintenance. To remove and replace
any failed module, follow the instructions in Removal and Installation Proce-
dures, also part of section 6. After isolating a faulty module, replace it with a
fully-tested module obtained from the factory. Section 10, Mechanical Parts
List, contains part number and ordering information for all replaceable modules.
