Replacing A Component

The phone module (PHM) has registered a fault on the internal GSM antenna.

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults may be due to interference upon start-up or may be another type of fault that can recur at different times. The fault is evaluated depending on how it occurs. If the fault recurs, replace the phone module (PHM).

In the event of a permanent fault, replace the phone module (PHM).

Remedy as necessary.
