This document is intended for use by qualied service personnel only.
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.

ESD protECtioN
Nokia requires that service points have sufficient ESD protection (against static electricity) when
servicing the phone.
Any product of which the covers are removed must be handled with ESD protection. The SIM card
can be replaced without ESD protection if the product is otherwise ready for use.
To replace the covers ESD protection must be applied.
All electronic parts of the product are susceptible to ESD. Resistors, too, can be damaged by static
electricity discharge.
All ESD sensitive parts must be packed in metallized protective bags during shipping and handling
outside any ESD Protected Area (EPA).
Every repair action involving opening the product or handling the product components must be
done under ESD protection.
ESD protected spare part packages MUST NOT be opened/closed out of an ESD Protected Area.
For more information and local requirements about ESD protection and ESD Protected Area, contact
your local Nokia After Market Services representative.
This product is of superior design and craftsmanship and should be treated with care. The suggestions below
will help you to full any warranty obligations and to enjoy this product for many years.
• Keep the phone and all its parts and accessories out of the reach of small children.
• Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that
will corrode electronic circuits.
• Do not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.
• Do not store the phone in hot areas. High temperatures can shorten the life of electronic devices, damage
batteries, and warp or melt certain plastics.
• Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form
inside, which may damage electronic circuit boards.
• Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.
• Do not paint the phone. Paint can clog the moving parts and prevent proper operation.
• Use only the supplied or an approved replacement antenna. Unauthorised antennas, modications or
attachments could damage the phone and may violate regulations governing radio devices.
All of the above suggestions apply equally to the product, battery, charger or any accessory.

BAttEry iNforMAtioN
Note: A new battery’s full performance is achieved only after two or three complete charge and discharge cycles!
The battery can be charged and discharged hundreds of times but it will eventually wear out.
When the operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.
Use only batteries approved by the phone manufacturer and recharge the battery only with the chargers
approved by the manufacturer.
Unplug the charger when not in use. Do not leave the battery connected to a charger for longer than a week, since
overcharging may shorten its lifetime.
If left unused a fully charged battery will discharge itself over time Temperature extremes can affect the ability of
your battery to charge.
For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time to time by leaving the
product switched on until it turns itself off (or by using the battery discharge facility of any approved accessory
available for the product).
Do not attempt to discharge the battery by any other means Use the battery only for its intended purpose.
Never use any charger or battery which is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or
pen) causes direct connection of the + and - terminals of the battery (metal strips on the battery) for example
when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery
or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in summer or winter conditions, will reduce
the capacity and lifetime of the battery. Always try to keep the battery between 15°C and 25°C (59°F and 77°F).
A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged.
Batteries’ performance is particularly limited in temperatures well below freezing.
Do not dispose batteries in a re! Dispose of batteries according to local regulations (e.g. recycling).
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.
•
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.
