4 General Information
Scope of Section 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.
4.1 Repair Levels and Website Access
Repair Levels This manual covers level-1 and level-2 repairs of TP9100 radios.
Level-1 repairs comprise the replacement of main boards and other parts
of the radio, including replacements of the non-SMT components:
■ power/volume potentiometer
■ 16-way/3-way selector switch
■ antenna SMA connector.
Level-2 repairs comprise repairs of main boards, except for the following
special items:
■ digital circuitry (IC701, IC703, IC704, and IC705)
■ CODEC 1 (IC204).
Important The main board is complex and should be serviced only by
accredited service centers (ASC). Repairs attempted
without the necessary equipment and tools or by untrained
personnel might result in permanent damage to the radio.
Accreditation of
Service Centers
Service centers 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 centers 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 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. All ASCs with the necessary
endorsements may carry out level-1 and level-2 repairs of these radios,
whether under warranty or not.
Skills and Resources
for Level-1 Repairs
For level-1 repairs basic electronic repair skills are sufficient. Apart from the
standard tools and equipment of any service center, certain torque drivers
are required as well as a service kit.
