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 ELEC-
TRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYS-
TEMS. 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 CELLU-
LAR TELEPHONES, MAY INTERFERE WITH THE FUNCTIONALITY OF INADE-
QUATELY 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 dam-
age may result.
4. Use only approved components as specified in the parts list.
5. Ensure all components, modules screws and insulators are correctly re-fit-
ted after servicing and alignment. Ensure all cables and wires are reposi-
tioned 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
protection. 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 compo-
nents 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.
