1.4 General Servicing Information
1.4.1 Repair Levels
This manual covers level-1 and specific level-2 repairs of TB8100
equipment. Level-1 repairs comprise the replacement of circuit boards and
plug-in cards; level-2 repairs comprise replacement of the RF power
transistors in the PA.
1.4.2 Accreditation of Service Centres
Service centres that wish to achieve Accredited Service Centre (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 Tait Electronics Limited 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
TB8100 equipment 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 TB8100 equipment. All ASCs with the
necessary endorsements may carry out level-1 and level-2 repairs of TB8100
equipment, whether under warranty or not.
1.4.3 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, certain torque drivers
are required, as well as a Service Kit, Calibration Kit (with dongle), and
Calibration and Test Unit (CTU).
1.4.4 Skills and Resources for Level-2 Repairs
For level-2 repairs expertise is required in handling and replacing insulated
gate FET transistors.
