SAFETY AND PRECAUTIONS

Turn off your cellular telephone when in an aircraft. The

use of cellular telephones in an aircraft may be dangerous

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.

Turn off your 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.

There may be a hazard associated with using your cellular

telephone close to personal medical electronic devices,

such as hearing aids and pacemakers.

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.

Attaching and Removing a Battery

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

Battery

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

Battery

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.

3. Batteries and Recharging

9

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.

3. Batteries and Recharging

10

Using Other Chargers

There is a number of other chargers available that can be

used to recharge a battery.

Some of these chargers are connected to the socket at the

bottom of the phone, allowing the battery to remain

attached to the phone.

Such a charger both recharges the battery and supplies

power to the phone. The recharging is controlled by the

phone, which must be turned on.

To indicate that recharging is in progress, the battery icon

on the right of the display is filled and emptied continuously.

The battery meter will not be shown unless the PIN has

been entered.

Conditioning a Battery

A battery that is delivered with the phone is not charged.

There may, however, be enough power to turn the phone

on.

To obtain best battery performance and long battery life,

you should condition the battery.

Also a used battery that has been stored for a long period

of time may require conditioning to retain its normal

capacity.

To condition a battery properly, recharge and discharge it

completely three times in succession.

To discharge a battery completely, proceed as described in

the section Battery Discharge earlier in this chapter.

There is another method to discharge a battery. Refer to

the description of the Info menu in Chapter 5. Using

Menus.

Battery Care and

Maintenance

A battery has a long maintenance-free service life if

properly treated.

●

Never let a battery get into contact with metal objects that

may short-circuit the battery poles, for example a bunch of

keys in a pocket.

●

A battery may explode if disposed of in a fire.

●

Do not disassemble a battery.

●

If you suspect a battery of not working properly, take it to

an authorised dealer.

●

Avoid recharging a battery before the low battery alarm

has been issued. Should you often do so, the battery’s

ability to accept a charge will be impaired, with the result

that the battery can only be used for shorter and shorter

periods between recharges. Such a battery can, however,

be conditioned using the method described above.

A hint:

If you are uncertain of the state of charge of a battery,

attach the battery to the phone. Press and hold down the

ON/OFF key.

If the phone does not come on, the battery is probably

empty.

3. Batteries and Recharging
