SAFETY AND PRECAUTIONS

●Switch off your cellular telephone when in an aircraft.

The use of cellular telephones in an aircraft may be dan-

gerous to the operation of the aircraft, disrupt the cellular

network and is illegal. Failure to observe this instruction

may lead to suspension or denial of cellular telephone

services to the offender, or legal action, or both.

●Users are advised to switch off the cellular telephone

when at a refuelling point.

●Users are reminded of the need to observe restrictions on

the use of radio equipment in fuel depots, chemical

plants, or where blasting operations are in progress.

●A hand-held microphone or telephone handset should not

be used by the driver while the vehicle is moving, except

in an emergency. You should only speak into a fixed,

neck slung or clipped-on microphone when it would not

distract your attention from the road. Do not stop on the

hard shoulder of a motorway to answer or make a call,

however urgent.

●There may be a hazard associated with using your GSM

telephone close to personal medical electronic devices,

such as hearing aids and pacemakers.

●Operation of your GSM telephone close to other elec-

tronic equipment, such as televisions, radios and per-

sonal computers may cause interference.

●Use only Basic Charger 4213 and AC/DC Converter

4214, Rapid Charger 4219, or Multi Charger 4221 and

AC/DC Converter 4222 with this telephone. Other usage

will invalidate any approval given to this telephone and

may be dangerous.

Introduction

This digital handheld cellular telephone is designed for use

on a GSM (Global System for Mobile communications)

network.

The GSM standard is the result of many years of

collaboration between the telecommunications authorities of

different European countries. This unique cooperation will

result in GSM networks being installed all over Europe as

well as in countries all over the world. This will allow you to

use your phone wherever you travel, for business or

pleasure.

The phone is small and light and simple to use. After you

have turned it on, you can use it in much the same way as

any other telephone.

The phone has an antenna which can be unfolded so that it

points directly upwards and, when not in use, can be folded

down completely.

Before holding the phone to your ear, ensure that

the antenna is unfolded completely.

About this manual

This manual is provided to help you use your phone. Keep

it handy to

answer questions you may have.

The next chapter, Basic Operation, describes the most

essential operations: Turning the phone ON/OFF,

making calls and answering calls.

Having learnt to perform these operations, you should read

the third chapter, Details on the Display and Keys, to learn

more about the display, with its status indicators, and the

functions of the various keys. The phone’s aud-

ible and visual signals are dealt with, too.

Then you can go on to read about the more advanced

functions, such as storing phone numbers and

accompanying names in memory, recalling phone numbers

from memory, DTMF signalling, and using the Special

Functions of the phone.

You should pay particular attention to the chapterBatteries

and Recharg-

ing because correct care will prolong the life of a battery

and also the length of time between recharging.

The Problems You Can Solve chapter at the end of the

manual could save the cost of unnecessary service.It lists

some simple things to be checkedbefore calling for service

personnel.

ON.

This is called PIN Check. Refer to the chapter Special

Functions.

an electronic lock to protect against unauthorized use of the

phone in the event of a theft. Refer to the chapterSpecial

Functions.

other than English. Refer to the chapterSpecial Functions.
