safetyinformation. Note also the following:
Warnings:
1. 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/MANUFACTURERTO DETERMINE THE IMMUNITY OF VEHICLE
ELECTRONIC SYSTEMS TO RF ENERGY.
2. THE HANDPORTABLE TELEPHONE MUST NOT BE OPERATED IN AREAS LIKELYTO CONTAIN
POTENTIALLY EXPLOSIVE ATMOSPHERES, EG PETROL STATIONS (SERVICE STATIONS),
BLASTING AREAS ETC.
3. OPERATION OF ANYRADIO 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 alignmentmust be undertaken by qualified personnel only.
2. Ensure all work is carriedout 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.
4. 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 protectionmust be applied.
All electronic parts of the product are susceptible to ESD. Resistors, too, can be damaged by
static electricitydischarge.
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

5. CARE AND MAINTENANCE
This product is of superior design and craftsmanship and should be treated with care. The suggestions below will help
you to fulfill any warrantyobligations and to enjoy this productfor 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 ormoisture 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 onlythe supplied or an approved replacement antenna. Unauthorised antennas, modifications or attachments
could damage the phone and mayviolate regulations governing radio devices.
All of the above suggestions apply equally to the product, battery, charger or anyaccessory.
6. 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 onlywith the chargersapproved 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 batteryonly for its intended purpose.
Never use anycharger or batterywhich 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 batteryin your pocketor purse. Short-circuiting the terminals maydamage the batteryor 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
capacityand lifetime of the battery. Always tryto keep the batterybetween 15°C and 25°C (59°F and 7 7°F).
A phone with a hot or cold battery maytemporarilynot work, even when the battery is fully charged.
Batteries’ performance is particularlylimited in temperatures well below freezing.
Do not dispose batteries in a fire! Dispose of batteries according to local regulations (e.g. recycling).
Do not dispose as household waste.
