ESD production
Nokia requires that product service points have sufficient ESD protection
(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 Services representative.

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 warranty obligations and to enjoy this product for many years.
zKeep the phone and all its parts and accessories out of the reach of small children.
zKeep the phone dry. Precipitation, humidity and all types of liquids or moisture can contain
minerals that will corrode electronic circuits.
zDo not use or store the phone in dusty, dirty areas. Its moving parts can be damaged.
zDo not store the phone in hot areas. High temperatures can shorten the life of electronic devices,
damage batteries, and warp or melt certain plastics.
zDo 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.
zDo not drop, knock or shake the phone. Rough handling can break internal circuit boards.
zDo not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.
zDo not paint the phone. Paint can clog the moving parts and prevent proper operation.
zUse only the supplied or an approved replacement antenna. Unauthorized 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.

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 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 that 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 of batteries in a fire!
Dispose of batteries according to local regulations (e.g. recycling). Do not dispose as household waste.
