SERVICE INFORMATION

Servicing the Handportable Terminals

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 Terminals are programmed at the factory. They cannot be tuned at the field service
level.
Level 3 Maintenance
Level 3 maintenance can only be done at the Motorola Service Centre/Depot. To find out
