3. If the main-board assembly has been replaced, level-1 service centres

Task 2 —
Enable Software
Features (SFE)
If the main-board assembly has been replaced, ensure that the correct
software features, if any, are enabled for the Customer. If software features
need to be enabled, a special licence file is required for the replacement
main-board assembly. The file must allow for the enabling of the same
software features as in the original assembly. Proceed as follows:
1. If it was possible to read the software features in “Obtain the Details
of the Software Feature Enabler (SFE)” on page 153, go to Step 2.
If it was not possible, go to Step 3.
2. Reading the software features reveals if any software features are
enabled for the radio under repair. If there are, go to Step 3. If there
are none, go to Task 3
.
3. Technicians not at a CSO should contact their CSO regarding the
radio’s software features. Technicians at CSOs should contact
Technical Support at TEL.
4. Supply the serial number of the radio under repair, and the serial
number of the replacement main-board assembly (located on a label
on the main-board assembly).
5. If it is known that the radio had software features enabled, go to
Step 6. Otherwise go to Step 7.
6. Ask the CSO (or TEL) for a licence file for the replacement main-
board assembly. The CSO will supply the required file. Go to Step 8.
7. Ask the CSO (or TEL) if the radio under repair had any software
features enabled, and if so, to send a licence file for the replacement
main-board assembly. The CSO (or TEL) will either indicate that the
radio had no software features enabled or supply the required file. If
the radio had no software features enabled, go to Tas k 3
. If the
required file was supplied, go to Step 8.
