76 General Information TB7100 Service Manual

Important The circuit boards in the base station 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 base station and void the
warranty.
Accreditation of
Service Centres
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 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, 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 centre, special test equipment
and certain torque drivers are required.
Skills and Resources
for Level-2 Repairs
For level-2 repairs, expertise is required in SMT repairs of circuit boards
with a very high complexity and extreme component density. Apart from
the tools and equipment needed for level-1 repairs, the standard SMT repair
tools are required. A can-removal tool is strongly recommended but not
mandatory.
Website Access To carry out level-1 and level-2 repairs, service centres need access to the
secured portion of the Technical Support website. There are different access
levels; those required for level-1 and level-2 repairs are:
■ level-1 repairs: associate access
■ level-2 repairs: ASC and Tait-only access
Log-in passwords are needed for associate and Tait-only access; Technical
Support supplies service centres with the necessary log-in information.
(The unsecured portion of the Technical Support website is accessible to the
general public. This type of access is called public access, and no log-in
password is required.)
