WARNINGS AND CAUTIONS

Warnings and Cautions
Please refer to the phone's user guide for instructions relating to operation, care and maintenance including impor-
tant safety information. Note also the following:
Warnings:
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 VEHI-
CLE 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 MANUFACTUR-
ER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS. OTHER ELECTRONIC EQUIPMENT MAY ALSO BE SUBJECT TO
INTERFERENCE.
Cautions:
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.

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.
Xenon flash - Handling instruction
With an undamaged module there is no possibility of an electric shock. However, the possible damage cannot
always be seen and therefore insulating glows should be always worn, when handling the Xenon module.
Disassembling the module is never allowed, because there is no way to fully discharge the module and also
repairing is impossible.
Care must be taken, when module is removed from the phone, because the flex is quite sensitive and can be
broken during removing. The flex should also not be bended or twisted unnecessarily.
The Xenon module includes electrolytic capacitor charged to voltage of 320V. Energy stored in the capacitor is
1.0...1.5J immediately after charging. If exposed to an electric shock it will most likely feel very nasty
on fingers. Possible risks causing an electric shock in a xenon module are:
• Broken flex between capacitors and lamp unit. The damage may be not visual.
• Broken molding on the lamp unit or capacitors.
• Cover window broken and xenon lamp exposed to the user.
