INTRODUCTION1.

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:cc-ts-rc.documentation@nokia.com
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 MANAGEMENT SYSTEMS
1. 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 POTENTIALLY EXPLOSIVE
2. 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.
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 has to take care of all precautions, which are mentioned in the service level related “Service Partner Requirements”, available on NOKIA Online. Also see ESD Protection Requirements in this Service Manual.

GENERAL REPAIR INFORMATION2.

In this section the technician will get some general hints how to carry out repairs:
To familiarize oneself with NOKIA product read the tutorials or user guide on www.nokia.com -->Support-->
• Phones, by selecting the Phone Model. Before starting the repair you must take care of ESD precautions like being in your ESD Protected Area and con-
• necting your wristband. Use gloves to avoid corrosion and fingerprints.
• Protect windows and displays with a film to avoid dust and scratches.
• When cleaning the LCD Module any lint-free cloth can be used (e.g. Micro-Fibre cloth).
• 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. Mechanical parts (except shielding lids and bent parts), which didn’t repair the failure, can 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 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 connec-
• tors or switches) and resolder them if necessary (Level 2 only). Remove redundant soldering flux after repair.
• Meet the torque requirements when assembling the unit (see also the document “torques for transceiver as-
• sembly” on NOKIA Partner Web Site/NOKIA Online). 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. A SIM card is needed for all GoNoGo tests.
• When doing the fault log entries, always note the Item code, which caused the malfunction. Also, fill in the ap-
• propriate part code from the assembly, if needed. Please be aware that some malfunctions could be software related and solved by an update.
MGR
There are several documents available on NOL, which have to be followed:
• First, take care for the latest content pages of Service Bulletins, which are always available for each folder on
• NOKIA Online. This is also important to recognize, if existing documents have become invalid.
• The service level indicator at the bottom of each document tells the appropriate destination.

GONOGO TEST16.

To test the Camera, Bluetooth and IRDA functionality refer to the phone User`s
guide.
The User´s Guide is available on www.nokia.com.
Before starting the
GoNoGo test, check that
camera window is clean.

Bluetooth test
You need another Bluetooth device (e.g. 6230) to do a GoNoGo test. Make sure that Bluetooth is activated in the reference unit. The distance of the devices should be not more than 5m from each other.
Infrared test
You need another infrared device (e.g. 6230) to do a GoNoGo test. The infrared windows of the devices must be directed to each other and should have a distance of approximate 15 cm. Make sure that infrared is activated in receiver device.
Warning: Do not point the IR (infrared) beam at anyone’s eye or allow it to interfere with other IR devices. This device is a Class 1 Laser product.
