This section discusses the two repair levels covered by the service manual,
details concerning website access, the tools, equipment and spares required,
and the setting up of the necessary test equipment. General servicing
precautions are also given, as well as details of certain non-standard SMT
techniques required for level-2 repairs.
This manual covers level-1 and level-2 repairs of the radios. Level-1 repairs
comprise the replacement of control-head boards, main-board assemblies,
and other parts of the radio; level-2 repairs comprise repairs of control-
head boards and, except for special items, main-board assemblies.
The special items are:
digital board
RF PAs (Q309 and Q310)
CODEC 1 (IC204)
copper plate.
Replacements of the connectors and volume-control potentiometer on the
control-head board are level-1 repairs. Replacements of the connectors on
the main-board assembly, however, are level-2 repairs because these repairs
entail the disassembly of the main-board assembly.
Important
The circuit boards in the radio are complex. They should
be serviced only by accredited service centres (ASC).
Repairs attempted without the necessary equipment and
tools or by untrained personnel might result in permanent
damage to the radio and void the warranty.
Service centres that wish to achieve ASC status should contact Technical
Support. They will need to provide evidence that they meet the criteria
required for accreditation; Technical Support will supply details of these
criteria. These centres must then make available suitable staff for training by
TEL personnel, allow their service facilities to be assessed, and provide
adequate documentation of their processes. They will be accorded ASC
status and endorsed for repairs of the radios after their staff have been trained
and their facilities confirmed as suitable. Existing ASCs need to apply for and
be granted an endorsement for repairs of the radios. All ASCs with the
necessary endorsements may carry out level-1 and level-2 repairs of these
radios, whether under warranty or not.
