Member: 3309 Status: Offline Thanks Meter: 2 | Ericsson T28 and T29 network signal jumping! One my friend confirms - that faulty by PA! But I distrust in this , I had several telephones Ò28 with faulty PA - they discharge the battery and were not included! Help to understand - Necessary to change PA or no? That else can be reason of such defect ? |
