Introduction
This section is a summary of experiences the NPE-4 R&D team made during the develop-
ment. It covers some errors or wrong configurations and their symptoms as well as
advice for problem solving. The section is seperated into two main parts the Baseband
troubleshooting and the RF troubleshooting, however, it is advisable to read both parts.
Baseband Troubleshooting
Phone is dead
This means that the phone does not use any current at all when supply is connected and/
or powerkey is pressed.
It is assumed that the voltage supplied is 3.6 VDC. The UEM will prevent any functional-
ity what so ever at battery/supply levels below 2.9 VDC.
