“Service Schematics” was created with focus on customer care.

The purpose of this document is to provide further technical repair information for

NOKIA mobile phones on Level 3/4 service activities.

It contains additional information such as e.g. “Component finder”,

“Frequency band table” or “Antenna switch table”.

The “Signal overview” page gives a good and fast overview about the most important signals and voltages on board.

Saving process time and improving the repair quality is the aim of this document.

It is to be used additionally to the service manual and other training or service information such as Service Bulletins.

All measurements were made using following equipment:

Nokia repair SW	: Phoenix version A14 2004.16.4.47
Oscilloscope	: Fluke PM 3380A/B
Spectrum Analyzer	: Advantest R3162 with an analog probe
RF-Generator / GSM Tester	: Rhode & Schwarz CMU 200
Multimeter	: Fluke 73 Series II
