Introduction

IMPORTANT:

This document is intended for use by authorized NOKIA service centers only.

The purpose of this document is to provide some further service information for NOKIA 3210 phones.

It contains a lot of collected tips and hints, to find failures and repair solutions easily.

I will also give support to the inexperienced technicians.

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

We have build it up based on fault symptoms (listed in "Contents") followed by detailed description for further

analysis.

It is to be used additionally to the service manual and other service information

like Service Bulletins, for that reason it doesn't contain any circuit descriptions or schematics.

All measurements are made with using of following equipment:

Nokia repair SW : Wintesla Version 6.10

DLL version : NSE8/9 version 2.41.05

Nokia Module Jig : MJS-13

Digital multimeter : Fluke 73

Oscilloscope : Hitachi V-1565; Fluke PM 3380A

Spectrum Analyzer : Advantest R3361C with an analogue probe

RF-Generator / : Rohde & Schwarz CMD 53

GSM Tester

While every endeavour has been made to ensure the accuracy of this document, some errors may exist. If any

errors are found by the reader, NOKIA should be notified in writing, using following procedure:
