Features (SFE)
If the main board 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.
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 129, go to Step 2.
If it was not possible, go to Step 3.
2. Reading the software features will have revealed if any software
features were enabled for the radio under repair. If there were, go to
Step 3. If there were none, go to Ta s k 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 (located on a label on the
main board).
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. The CSO will supply the required file. Go to Step 8.
