Version 1.1

6

Nokia requires that service points have sufficient ESD pr otection (against s tatic electricity) when servicing the phone. Any product of which the covers are removed m ust be handled with ESD protection. Th e 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 metallised protective ba gs 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 phon e and all its parts and accessories out of the r each of small children.

• Keep the phone dry. Precipitation, humidity and all types of liquids or moisture can

contain minerals that will corrode electronic c ircuits.

• 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.

Service Manual L1&2

• Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form inside, which may dama ge electronic circuit boards.

• Do not drop, knock or shake the phone. Rough handling can break internal circuit boards.

• Do not use harsh chemicals, cle anin g solvents, or strong detergents to clean the phone.

• Do not paint the p ho ne. 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 dama ge the phone and may violate regulations governing radio devices.

All of the above suggestions apply equally to the pro duct, 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 th e 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).

Service Manual L1&2

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 da maged. 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 batter y (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 e 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. Battery performance is particularly limited in temp eratures 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.
