About the Phone
This digital handheld cellular telephone is designed for use
on a GSM (Global System for Mobile communications)
network.
GSM is the new international standard for cellular
communication. It covers most European countries and
many other parts of the world. This lets you use your phone
wherever you travel, for business or pleasure.
The phone is very 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. However, a cellular phone operates
by using radio signals which can be subject to interference.
It may sometimes happen, therefore, that you need to move
the phone to a position where you can obtain a better radio
signal. Indoors, it is usually best to use the phone near a
window.

About the Manual
This manual is provided to help you use your phone. Keep
it handy to answer questions you may have.
Chapter 2. Getting Started describes how to make your
phone ready for use.
Correct care will prolong the life of a battery and also the
length of time between recharging. You should, therefore,
pay particular attention to Chapter 3. Batteries and
Recharging.
Chapter 4. Basic Operation describes how to make calls
and how to answer calls.
Having learnt how to perform the most essential operations,
you can go on to read Chapter 5. Using Menus. It
describes functions which you can use to adapt your phone
to your personal needs. It also describes how to create a
personal Phone Book; you can store both numbers and
names.
Chapter 6. Accessories deals with optional equipment that
can be used with the phone, for example a handsfree
system for use in a car.
Chapter 7. Problems You Can Solve lists some simple
things you should check before calling for service
personnel. This could save the cost of unnecessary service.

SIM -- Subscriber Identity Module
When you become a subscriber of a network operator, you
will obtain a Mini SIM Card.
The Mini SIM Card must be inserted into the phone.
Otherwise, the phone cannot be used. However, calls to the
emergency phone number 112 can be made without the
card being inserted, provided a GSM network is in range.
The card contains a computer chip with your personal data,
such as your subscriber number and the name of your
operator’s network, also referred to as your ‘‘home’’
network. Besides your ‘‘home’’ network, you may use your
phone also in GSM networks in other countries.
The computer chip also includes a memory, which you can
use as your personal phone book to store and recall phone
numbers.
PIN -- Personal Identification Number
Your SIM is protected by a unique 4- to 8-digit PIN, which
must be entered each time the phone is turned ON. This is
called PIN Check.
The Access menu of your phone allows you to deactivate
the PIN Check. It also allows you to choose another PIN.
Refer to Chapter 5. Using Menus.
Phone Lock
The PIN Check protects the SIM card only, not the phone
itself. The Access menu allows you to enable an electronic
lock to protect against unauthorised use of the phone in the
event of a theft. Refer to Chapter 5. Using Menus.
Key Lock
You can lock the keypad so that unintentional key action
has no effect if the phone is turned on. This is useful when
you, for example, are carrying the phone in a pocket or a
handbag. Refer to the description of the Key Lock menu in
Chapter 5.
Clock
The time of the day is shown continuously in the display.
When your phone is delivered, the clock is normally not set.
The Clock menu lets you set the clock. Refer to Chapter 5.
Display Language
Your phone is normally delivered with English text in the
display.
The Settings menu allows you to select a language other
than English. Refer to Chapter 5.

Battery Types
The batteries that can be used with this phone are of the
NiMH type. (NiMH stands for Nickel Metal Hydride.)
Compared to the commonly used NiCd (Nickel Cadmium)
batteries, the NiMH batteries have a higher capacity and
they are much more friendly to the environment.
Battery Meter
The battery meter, to the right in the
display, reflects the state of charge of the
battery attached to the phone.
Low Battery Alarm

As a reminder that the battery soon
needs recharging or replacing, an alarm
signal (a long beep) sounds and the
message Battery Low appears for ten
seconds in the display.
In addition, the indicator light on the top edge of the phone
starts blinking red.
If the phone is left on, after the low battery alarm has been
issued several times, it will turn itself off when the battery is

no longer able to power it satisfactorily. Then, it is not
possible to turn the phone on again. Instead, the battery
must be recharged, or replaced with a charged one.
Low battery alarm during a call:
If the low battery alarm is issued when a call is in progress,
you should end the call as quickly as possible. If the call
continues, the phone will turn itself off after a short period.
Battery Discharge

discharge
When the phone turns itself off, the
message Battery discharge appears in
the display and the indicator light on the
top of the phone shows a steady red
light. This indicates that the phone is now
discharging the battery.
If you have the opportunity, let the battery remain attached
to the phone, to discharge it completely. Do not remove it
until the message Battery discharge and the red light go
out. Not until then is the battery completely discharged.
Recharging a battery completely, will help to enhance its
lifetime.

Recharging a Battery
Using the Standard Charger
The charger, delivered with the phone, is to be used
indoors together with an AC/DC converter.
Use only the AC/DC converter provided with the charger.
Use of any other AC/DC converter may be dangerous.
Never recharge a battery with the basic charger when the
ambient temperature is below 5 °C or above 40 °C.
Connecting the standard charger:
1. Connect the AC/DC converter to the charger.
2. Plug the AC/DC converter into a mains socket. The
indicator light on the charger should flash to inform
that power is connected properly.
Recharging a battery:
1. Attach the battery in the same way as you would
attach it to the phone.
A red light on the charger comes on to indicate
that the battery is being recharged. An empty
standard battery will be fully recharged within
approximately 2 hours; an empty high-capacity
battery within approximately 4 hours.
2. A green light replaces the red light when
recharging is complete, and you can now remove
the battery.
However, no harm will come to the battery if left in
the charger. When a battery is fully recharged, the
charger changes to trickle-charging the battery.
