3. 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:

3.1 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/MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE

ELECTRONIC SYSTEMS TO RF ENERGY.

2. THE HANDPORTABLE TELEPHONE 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.

3.2 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.

Service Manual Level 1&2

6 CONFIDENTIAL

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 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.

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 fulfil 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,

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.

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 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 fire! Dispose of batteries according to local regulations (e.g.

recycling).

Do not dispose as household waste.
