Task 1 —
Repair
The fault diagnosis will have resulted in the repair or replacement of the
main-board assembly. This section describes the steps after completion of
the fault diagnosis:
1. Use the programming and calibration applications to load the pro-
gramming and calibration files read or set-up in “Initial Tasks”.
Note If the radio had to be reprogrammed with a default programming
file, the following additional actions are required: If the radio is to
be returned direct to a Customer who has no programming facil-
ities, the appropriate programming file needs to be obtained and
uploaded (or the data obtained to create the file). If the radio 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 radio appropriately.
Note If the main-board assembly has been replaced, certain software
features may need to be enabled before the programming file can
be loaded. See Task 2 on page 148.
2. Test the radio as described in “Final Test” on page 149.
It may be necessary to also re-calibrate to make the radio functional,
in particular if the main-board assembly had to be replaced or if a
default calibration file had to be loaded. Refer to the online help of
the calibration application.
