4.1 General
4.1.1 Scope
This document briefly describes the TG Service software for Benefon products
belonging to the Twin Generation, namely Benefon Twin, Benefon Twin DS, Benefon
Q, Benefon Esc! and Benefon Track.
4.1.2 Hardware requirements of TG Service software
The use of TG Service software requires a proper service adapter ( APD 70 ).
It’s advisable connect the service PC to also a Rohde&Swartz CMD 55 or a Wavetek
4400M. This is required for automatic tuning.
4.1.3 Revision history
This document is based on TG Service software version 2.1.
4.2 Getting started
First connect the service adapter to the PC and phone. Check that the COM port setting is correctly set in TG Service software in menu item “Device->Options->Phone”.
The TG Service software works best on a phone without a SIM. During power-up:
reading the contents of a SIM card uses quite a lot of phone’s processing power and
during this time the Service mode software works slowly. Using TG Service software
without a SIM card in the phone overcomes this problem.
