Enter the Setup menu by pressing »MENU«

Select »Security«

Entering the Security menu gives you different

possibilities of preventing misuse of your SIM

card and your telephone, e.g. if your phone is

lost or stolen:

»PIN code«

»SIM lock«

»Network password«

»Encryption indication«

»Line lock«

PIN code

In this sub menu you can select a PIN code (4

to 8 digits) to be entered each time you switch

on your phone. If you have already selected a

PIN code you also have the choice of disabling

it again or changing it to another code.

If you enter an invalid PIN code three times,

your SIM card will be blocked, and to unblock

it you have to enter the PUK code supplied by

your network operator. This procedure prevents

unauthorised persons from working out your

PIN code by repeatedly entering different

combinations of numbers.

The display will inform you how many tries

you have left before the SIM card is blocked. If

you enter an invalid PUK code 10 times, your

SIM card will be permanently blocked and you

have to contact your network operator.

Some SIM cards use a PIN2 code for access-

ing special functions. Contact your network

operator for further information on PUK2 and

PIN2 codes.

SIM lock

You can link your telephone and your SIM

card together. This means that if, for instance,

your phone is stolen, it cannot be used together

with another SIM card. To enable this feature

you just turn it on and then enter a 6 to 16-digit

code of your own choice.

For your own sake remember to write down this

code to be able to deactivate the lock at a later

time. You have 10 attempts before the phone is

blocked

Network password

If you subscribe to a call barring service your

network operator will have supplied you with a

4-digit password. If you want to change it,

select this sub menu.

Encryption indication

Encryption means that the network encrypts

the conversations to make it difficult for

unauthorised persons to listen in on them. If

you connect to a network which does not

support encryption, you will get a warning in

the display when trying to make a call. You

have the option of turning on and off the net-

work warning by selecting this sub menu.

Line lock

If you have Alternate Line Service on your

SIM card you can restrict the outgoing use to

only one of these lines. Activate the line lock in

this sub menu and enter a 4 to 8 digit lock code

of your own choice. To shift back to the other

line you have to re-enter this code.

Enter the Setup menu by pressing »MENU«

Select »Call timers and charge«

The Call timers and charge menu offers you

the possibility of checking duration and cost of

your calls in different ways:

»Last call«

»Total calls«

»Reset timers and charge«

»Show timer and credit«

»Call charge«

Last call

Informs you about the duration of your last

call. You may also be able to see the cost of

your last call, but this feature demands that

your network supports it, and that you have

entered a unit price and the actual currency in

the sub menu Call charge (see below).

Total calls

Informs you about the duration of all calls

made with your SIM card since the timer was

last reset. The conditions for also seeing the

cost of these calls are identical with the

conditions mentioned above in the Last call

sub menu.

Reset timers and charge

Resets your timers, so that the call duration

counter is set to zero. You may be asked to

enter your PUK2/PIN2 code.

Show timer and credit

You can select whether you want the Show

timer function to be on or off. If you turn it on,

your telephone will display the actual duration

of an ongoing conversation. The conditions

for also seeing the cost are identical with the

conditions mentioned above in the Last call

sub menu.

Call charge

If your network supports this feature, this is

where you deal with the call charge. To enter or

change call charge and currency you will be

requested to enter your PUK2/PIN2 code. You

have the following options:

»Call charge maximum«

»Call charge unit price«

»Call charge currency«

»Call charge remaining«

Call charge maximum

Gives you the option of entering a maximum

call charge limit, so that when this maximum

has been reached no more phone calls can be

made.

Call charge unit price

This is where to enter the unit price (check with

your network operator).

Call charge currency

This is where to enter the currency of your call

charge.

Call charge remaining

The telephone can inform you about the

remaining call charge balance, if you have

entered a maximum call charge limit.
