1. INTRODUCTION

The purpose of this document is to help Nokia service levels 1 and 2 workshop technicians to carry out service to
Nokia products. This Service Manual is to be used only by authorized Nokia service suppliers, and the content of it
is confidential. Please note that Nokia provides also other guidance documents (e.g. Service Bulletins) for service
suppliers, follow these regularly and comply with the given instructions.

While every endeavor has been made to ensure the accuracy of this document, some errors may exist.
If you find any errors or if you have further suggestions, please notify Nokia using the address below:

mailto:[e-mail]

Please keep in mind also that this documentation is continuously being updated and modified, so watch always
out for the newest version.

Warnings and Cautions

Please refer to the phone’s user guide for instructions relating to operation, care and maintenance including
important safety information. Note also the following:

Warnings:

CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE

1.
MANAGEMENT SYSTEMS AND ANTI–SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT CONDITIONS, EMITTED RF
ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER/MANUFACTURER TO
DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY.
THE HANDPORTABLE TELEPHONE MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN

2.
POTENTIALLY EXPLOSIVE ATMOSPHERES EG PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.
OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE WITH

3.
THE FUNCTIONALITY OF INADEQUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE
MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY ALSO
BE SUBJECT TO INTERFERENCE.

PAGE 3 (20) Approved 1.0

MGR

Cautions:

1. Servicing and alignment must be undertaken by qualified personnel only.

2. Ensure all work is carried out at an anti–static workstation and that an anti–static wrist strap is worn.

3. Use only approved components as specified in the parts list.

4. Ensure all components, modules screws and insulators are correctly re–fitted after servicing and alignment.
Ensure all cables and wires are repositioned correctly.

Electrostatic discharge can easily damage the sensitive components of electronic products.
Therefore every Service Supplier has to take care of all precautions, which are mentioned in
the service level related “Service Partner Requirements”, available on Nokia Partner Web
Site/Nokia Online. Also see ESD Protection Requirements in this Service Manual.

2. GENERAL REPAIR INFORMATION

In this section the technician will get some general hints how to carry out repairs:

o

To familiarize oneself with Nokia product read the tutorials or user guide on www.nokia.com -->Support-->
Phones, by selecting the Phone Model.

o

Before starting the repair you must take care of ESD precautions like being in your ESD Protected Area and
connecting your wristband.

o

Use gloves to avoid corrosion and fingerprints.

o Protect windows and displays with a film to avoid dust and scratches.
o When cleaning the LCD Module any lint free cloth can be used (e.g. Micro-Fibre cloth).
o When cleaning the pads you have to use a soft cloth/ESD brush and Isopropanol. It is not allowed to use a

glass fiber pencil because it scratches the surface and will lead later on to corrosion.

o Mechanical parts (except shielding lids and bent parts), which didn’t repair the failure, can be reused, if they

are not soldered.

o When removing the shielding lids make sure to replace them with new ones, otherwise the high-frequency

leakage can have an influence on the device.
Always use original Nokia spare parts.
Check the soldering joints of the parts, which are concerned regarding the indicated error (e.g. soldered
connectors or switches) and resolder them if necessary (Level 2 only).
Remove redundant soldering flux after repair.

o Meet the torque requirements when assembling the unit (see also the document “torques for transceiver

assembly” on Nokia Partner Web Site/Nokia Online).

o Always use your own equipment for testing where you are sure that it works. E.g. if the customer complains

about charger function, please test the phone with your own charger to be sure if phone or charger causes the
malfunction.

o When doing the fault log entries, always note the Item code, which caused the malfunction. Also, fill in the

appropriate part code from the assembly, if needed.

o Please be aware that some malfunctions could be software related and solved by an update.

o There are several documents available on PWS/NOL - CarePoint, which have to be followed:

o First, take care for the latest content pages of Service Bulletins, which are always available for each folder on

Nokia Partner Web Site/Nokia Online. This is also important to recognize, if existing documents have become
invalid.

o The service level indicator at the bottom of each document tells the appropriate destination.
