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 protec-
tion (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 Ser-
vices 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 nor-
mal, 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 con-
ditions, 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 tempo-
rarily not work, even when the battery is fully charged. Batteries' performance is particu-
larly 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 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), mois-
ture 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, mod-
ifications 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 acces-
sory.
