Servicing MTM800 with Enhanced Control Head Mobile Units
Service for the mobile units is based on the substitution method; a faulty part is replaced by a
working one, providing quicker service to the customer. For example, if the controller board is faulty,
it is replaced. If the mobile requires more complete testing or servicing than that is available at field
level, it is sent to the European Radio Service Centre; where it is serviced, and returned to the
Regional Service Centre.
Level 1 and Level 2 Maintenance
This manual covers Level 1 and Level 2 Maintenance: at Level 1 maintenance you replace the
transceiver and/or accessories and send the faulty transceiver and/or accessories to higher level of
maintenance; at level 2 maintenance a transceiver board is replaced.
The MTM800 mobiles are programmed at the factory. They cannot be tuned at the field service
level.
Level 3 Maintenance
All Radio Support Depots are level 3 service partners. The depots are capable of performing repairs
down to component level where retuning is required. Contact your local CGISS office for
information.
Replacement Parts
Damaged parts should be replaced with identical replacement parts.
For complete information on ordering required parts and kits, contact your local customer service
representative (see following pages).
