MANAGEMENT SYSTEMS AND ANTI–SKID BRAKING SY STEMS. 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 SY STEMS 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 PHY SICIAN OR THE MANUFACTURER OF THE

MEDICAL DEVICE IF Y OU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY

ALSO BE SUBJECT TO INTERFERENCE.

3. ESD PROTEC TIO N

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.

4. 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 d usty, 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 t he pho ne. Ro ugh 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 regulatio ns governing radio devices.

All of the above suggestions apply equally to the product, battery, charger or any

accessory.

5. BATTE RY INF ORM ATIO N

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 atte mpt 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. Shortcircuiting 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.
