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:

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 NECES-
SARY, 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 CON-
TAIN POTENTIALLY EXPLOSIVE ATMOSPHERES EG PETROL STATIONS (SERVICE STA-
TIONS), BLASTING AREAS ETC.
3. OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULAR TELE-
PHONES, 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.

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. Ensure solder, wire, or foreign matter does not enter the telephone as damage may
result.
4. Use only approved components as specified in the parts list.
5. Ensure all components, modules screws and insulators are correctly re-fitted after serv-
icing and alignment. Ensure all cables and wires are repositioned correctly.

ESD Protection

Nokia requires that phone repair places have sufficient ESD protection (against static
electricity) when servicing cellular phones.

A cellular phone, which is ready for use, can be handled normally without ESD protec-
tion. The SIM card and battery can be replaced in normal conditions of use.

To replace the color cover ESD protection must be applied, except for the phone covers
which can be replaced by the customer.

All electronic parts of the phone, including the display, 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 phone or handling the phone components must
be done under ESD protection.

ESD protected spare part packages MUST NOT be opened/closed out of an EPA.

For more detailed information about ESD protection and EPA, contact your local Nokia
After Market Services representative.
