The phone can not make calls

The phone can not be used to call even though the signal indicator on the phone there.

Repair procedures:

* Check first on the phone menu settings 'Call Settings' and 'Phone Settings'. Are settings correct?
* If the settings are correct, then we proceed to examine the path to the IC PA.
* If the path to a good PA IC, IC test whether PA itself is still functioning properly, if it does not work properly replace IC PA.
* If the PA IC has been replaced but still not able to make a call, we test the network for the phone manually, when the phone is sometimes able to find but sometimes not, panasi RF IC (HAGAR) first, if the problem persists then replace the RF IC (HAGAR )
