2. WARNINGS AND CAUTIONS
Please refer to the phone’s user guide for instructions relating to operation, care and
maintenance including important safety information. Note also the following:

2.1Warnings
1. CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE
MANAGEMENT SYSTEMS AND ANTI–SKID BRAKING SYSTEMS. 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 SYSTEMS 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 PHYSICIAN OR THE MANUFACTURER OF THE
MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY
ALSO BE SUBJECT TO INTERFERENCE.

2.2Cautions
1. Servicing and alignment must be undertaken by qualified personnel only.
2. Ensure all work is carried out at an anti–static workstation and that an anti–static wrist
strap is worn.
3. Use only approved components as specified in the parts list.
4. Ensure all components, modules screws and insulators are correctly re–fitted after
servicing and alignment.
5. Ensure all cables and wires are repositioned correctly

3. 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.

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 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.

5. 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.
