A PHYSICIAN OR THE MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS.
OTHER ELECTRONIC EQUIPMENT MAY ALSO BE SUBJECT TO INTERFERENCE.

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.
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.
