Task 1 —
Repair
The fault diagnosis will have resulted in the repair or replacement of a
module. This section describes the steps after completion of the fault
diagnosis:
1. If the transmitter or receiver module has been replaced, level-1
service centres should return the faulty module to the nearest ASC,
and level-2 service centres should return the module to the ISC, if
deemed necessary. Supply details of the fault and, if applicable, the
attempted repair. (The replacement module will have been factory-
calibrated.) Go to
Step 5 .
2. If the transmitter or receiver module has not been replaced, but was
repaired then replace any cans removed and reinstall the module into
the base station.
3. Reconnect the module to the test equipment and re-calibrate the
module. Refer to the online help of the calibration application.
4. Use the programming and application to load the programming and
files read or set-up in
“Initial Tasks” .
5. Use the calibration application to load the calibration files read or set-
up in

Note
If the base station had to be reprogrammed with a default
programming file, the following additional actions are required:
■
If the base station is to be returned direct to a Customer who has
no
programming facilities, the appropriate programming file
needs to be obtained and uploaded (or the data obtained to create
the file).
■
If the base station is to be returned to a Dealer or direct to a
Customer who does have programming facilities, the Dealer or
Customer respectively need to be informed so that they can
program the base station appropriately.
■
If the fault was with the customer’s data file, the customer needs
to be informed of this and the changes that were made.
6. Test the base station as described in “Final Test” on page 124 . It may
be necessary to also carry out the audio level adjustments as described
in the installation and operation manual.
