INTRODUCTION1.

The purpose of this document is to help NOKIA service levels 1 and 2 workshop technicians to service NOKIA products. This Service Manual must be used only by authorized NOKIA service suppliers. The content of it is confidential. Please note that NOKIA also provides other guidance documents (e.g. Service Bulletins) for service suppliers. Follow these regularly and comply with the given instructions.
While every effort 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:cc-ts-rc.documentation@nokia.com
Please keep in mind also that this documentation is continuously being updated and modified, so always watch out for the newest version.
Warnings and Cautions
Please refer to the phone’s user’s guide for instructions relating to operation, care, and maintenance, which include impor­tant safety information. Note also the following:
Warnings:
CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND
1. 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 CELLULAR TELEPHONE MUST NOT BE OPERATED IN
2. AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES, EG PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC. OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELEPHONES, MAY INTERFERE WITH THE
3. 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.
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.
5. Ensure all cables and wires are repositioned correctly.
Electrostatic discharge can easily damage the sensitive components of electronic products. Therefore, every Service Supplier must observe the precautions, mentioned in the appropriate “Service Partner Requirements”, available on NOKIA Online. Also see ESD Protection Require­ments in this Service Manual.

GENERAL REPAIR INFORMATION2.

This section provides useful repair information how to carry out repairs:
Make sure your testing equipment is functioning properly before beginning repair work.
To familiarize yourself with the NOKIA product read the tutorials or user’s guide on www.nokia.com -->Support-->
• Phones, by selecting the Phone Model. Before starting repairs you must observe ESD precautions such as being in your ESD Protected Area and connecting
• your wristband. Use gloves to avoid corrosion and fingerprints.
• Cover windows and displays with a protective film to avoid dust and scratches.
• Use a lint-free cloth (e.g. Micro-Fibre cloth) to clean the LCD.
• When cleaning the pads use a soft cloth/ESD brush and Isopropanol. Do not use a glass fiber pencil: this scratches the
• surface and will corrosion. Non-faulty mechanical parts (except shielding lids and bent parts or soldered components), may be reused if they are
• not soldered. When removing the shielding lids make sure to replace them with new ones, otherwise the high-frequency leakage
• can affect the device. Always use original NOKIA spare parts.
• Check the soldering joints of the parts concerned with regard to the fault symptom (e.g. soldered connectors or
• switches) and resolder them if necessary (Level 2 only). Remove excess soldering flux after repair.
• Observe the torque requirements when assembling the unit.
• Preferably use your own equipment for testing. E.g. if the customer complains about charger function, please test the
• phone with your own charger to determine if the malfunction is being caused by phone or charger causes the mal­function. A SIM card is needed for all GoNoGo tests.
• When doing the fault log entries, always note the Item code of the part that caused the malfunction. Also, fill in the
• appropriate part code from the assembly if needed. Please be aware that some malfunctions may be software related and solved by an update.
13.3.2006
There are several documents available on NOL which must be followed:
• First, pay attention to the latest content pages of Service Bulletins, which are always available for each folder on NOKIA
• Online. Make sure your documentation is up to date.
• The service level indicator at the bottom of each document displays the appropriate target group.
