4.1.1 General

The Benefon Vega has a special service operation mode for testing and tuning. In
this mode, all commands are sent via the serial communications bus to the phone.
The keypad of the phone cannot be used.
A PC application has been created to help in using the service mode. The applica-
tion can send command sequences needed in tuning procedures and store tuning
parameters on the EEPROM chip in the phone afterwards.
A service adapter is needed to connect the phone and PC.
