Access Codes

You can use the access codes described in this section to avoid unauthorised use of your phone and SIM card.

The access codes (except PUK and PUK2 codes) can be changed by using Menu 4-5-6. See the following section.

NOTE: Avoid using access codes similar to emergency numbers, such as 112, to prevent accidential dialling of the emer- gency number.

Security Code (5 digits)

The security code can be used to avoid unautho- rised use of your phone. The security code (se- curity code) is usually supplied with the phone. Change the security code before you start using your phone. Keep the new code secret and in a safe place, which is separate from the phone. The default code is 12345.

NOTE: If you key in an incorrect security code five times in succession, the phone will not accept the correct code for the next five minutes.

PIN Code (4 to 8 digits)

The PIN (Personal Identification Number) code protects your SIM card against unauthorised use. The PIN code is usually supplied with the SIM card. When the PIN code request is enabled (Menu 4-5-1), the code is asked each time the phone is switched on.

NOTE: If you key in a wrong PIN code three times in succession, key in the PUK code and press OK. Key in a new PIN code and press OK. Key in the new code again and press OK.

PIN2 Code (4 to 8 digits)

The PIN2 code, supplied with some SIM cards, is required to access some functions, such as charging unit counters. These functions are only available if supported by your SIM card.

NOTE: If you key in a wrong PIN2 code three times in succession, follow the same instructions as for the PIN code but this time using the PUK2 code.

PUK Code (8 digits)

The PUK (Personal Unblocking Key) code is re- quired to change a blocked PIN code. The PUK code may be supplied with the SIM card. If not, contact your local service provider for the code. If you lose the code, contact your service provider.

PUK2 Code (8 digit)

The PUK2 code, supplied with some SIM cards, is required to change a blocked PIN2 code. If you lose the code, contact your service provider.

Barring Password

The barring password is needed when using the ‘Call Barring’ function. You obtain the password from your service provider.

DTMF Tones

The phone can send DTMF tones to communicate with answering machines, computerised tele- phony services etc.
