Important:
This document is intended for use by authorized service centers only.
“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 nder”,
“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 additionaly 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 2006.34.2.156
Oscilloscope : Fluke PM 3380A/B
Spectrum Analyzer : Advanced R3162 with an analog probe
RF-Generator/GSM Tester : Rhode & Schwarz CMU 200
Multimeter : Fluke 73 Series II

A NEW FEATURE FOR ON-LINE USE
We have now linked those measurement points , which are related to the
oscillograms shown on the signal overview page. As example: clicking on the
measurement point guides you to the matching oscillogram on the signal overview
page. The next click onto the now shown signal guides you to the related measurem-
nt point on the module. Finally, a third click , now onto the measurement point on
the module, takes you back to the starting point inside the schematics.
Do you have further improvement ideas or would like to give us feedback?
