5.3 Final Inspection, Test and Administration
Remaining Tasks
This subsection discusses the servicing tasks remaining after the repair, or
attempted repair, of the radio:
■
final inspection
■
final test
■
final administration
If the radio could not be repaired, omit the first two tasks.
Final Inspection
After repairing and re-assembling the radio, make a final inspection of the
exterior to check that no mechanical parts were damaged during the
repair. Repeat the inspection given in
Subsection 5.1 (on page 107) .
Rectify any damage.
Final Test
Reconnect the radio to the test equipment. Test the radio to confirm
that it is fully functional again. The recommended tests are listed in
Table 5.1 to Table 5.3 . (The calibration application can be used for
many of these tests.) It is good practice to record the test results on a
separate test sheet. A copy of the test sheet can be supplied to the
Customer as confirmation of the repair.
Final Administration
The administration tasks following a successful repair of the radio are
discussed in the next paragraph. There will be cases, on the other hand,
where the radio could not be repaired for one of the following reasons:
■
fault not located
■
repair of fault failed
■
required repair is level-3 repair
In these cases level-1 service centres should return the faulty radio to the
nearest ASC, and level-2 service centres should return the radio to the
ISC. Supply details of the Customer, the fault and, if applicable, the
attempted repair.
Administration Tasks
The final administration tasks are the standard workshop procedures for
updating the fault database and returning the repaired radio to the
Customer with confirmation of the repair. With TM8100 radios,
however, additional tasks are necessary if:
■
faulty control-head board or main-board assembly is replaced
■
default programming file is used
These additional tasks are discussed further below.
