Warnings and Cautions

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

Warnings:

1. IF THE DEVICE CAN BE INSTALLED IN A VEHICLE, CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE 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.

2. THE PRODUCT MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES EG PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.

3. OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING

CELLULAR TELEPHONES, MAY INTERFERE WITH 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. Ensure solder, wire, or foreign matter does not enter the telephone as damage may result.

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

5. Ensure all components, modules screws and insulators are

correctly re-fitted after servicing and alignment. Ensure all cables and wires are repositioned correctly.

For Your safety

QUALIFIED SERVICE Only qualified personnel may install or repair phone equipment.

ACCESSORIES AND BATTERIES Use only approved accessories and batteries. Do not connect incompatible products.

CONNECTING TO OTHER DEVICES When connecting to any other device, read its user’s guide for detailed safety instructions. Do not connect incompatible products.

ESD protection

Nokia requires that product service points have sufficient ESD protection (against static electricity) when servicing products.

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.

Battery information

Note that 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 that 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 of batteries in a fire! Dispose of batteries according to local regulations (e.g. recycling). Do not dispose

as household waste.

Care and Maintenance

The product is a product of superior design and craftsmanship and should be treated with care. The suggestions below will help you to fulfill 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. Unauthorized

antennas, modifications 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.

General Repair Hints

This section provides general hints on repairs: Read the tutorials or user guide on www.Nokia.com > Choose your location >

Support > Product Support. Select the appropriate mobile terminal model to become familiar with the Nokia product.

 Take adequate ESD precautions before starting repairs, e.g. work in an ESD

Protected Area, and that an anti-static wrist strap is worn.

 Use gloves to avoid corrosion and fingerprints.  Protect windows and displays with a film to avoid dust and scratches.  Use a lint-free cloth when cleaning the LCD module (e.g. Micro-Fiber cloth).  Use a soft cloth/ESD brush and Isopropanol when cleaning the pads. Do not

use a glass fiber pencil as it will scratch the surface and will lead to corrosion.

 Reuse mechanical parts that are not soldered if they did not repair the failure

(except shielding lids and bent parts).

 Make sure to replace the shielding lids with new ones when removing them,

so that the high-frequency leakage does not affect the device.

 Always use original Nokia spare parts.  Check the soldering joints of the parts causing problems (e.g. soldered

connectors or switches) and resolder them if necessary (Level 2 only).

 Remove redundant soldering flux after repair.  Meet the torque requirements when assembling the terminal (see also

"Torques for transceiver assembly" document found on Nokia Online).

 Always use properly functioning test equipment to test to be sure if it is the

mobile terminal and not faulty equipment causing the malfunction.

 A UIM card is required for all Go-No-Go tests.  Make a note of the Item code causing the malfunction when making fault log

entries. Also complete the appropriate part code from the assembly if needed.

 Note that some malfunctions could be software related and resolved by a

software update.

 Refer to additional documents available on Nokia Online (NOL).

Note: Check Nokia Online (NOL) for latest news and files on a regular basis.
