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
1
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.

subscriber number, your ‘‘home’’ network and services you

not this PIN must be entered each time the phone is turned
ON.
This is called PIN Check. Refer to the chapter Special
Functions.

Special Function No. 20, Phone Lock allows you to enable
an electronic lock to protect against unauthorized use of the
phone in the event of a theft. Refer to the chapterSpecial
Functions.

the display will be in English.
Special Function No. 16 allows you to select a language
other than English. Refer to the chapterSpecial Functions.
Some of the functions described in this manual are
optional, and you may not have access to them.
