(Change phone code)

You define the phone code (4 to

8 digits) when you call up a phone- code protected function for the first time (e.g. Direct call, p. 37). It is then valid for all phone-code protected functions.

After the third unsuccessful attempt, access to the phone code and the functions that use it is denied. If this occurs, contact Siemens Service (p. 131).

Clear SIM card barring

If the PIN is entered incorrectly three times, the SIM card is barred. Enter the PUK (MASTER PIN) provided by your service provider with the SIM card in accordance with the instruc- tions. If the PUK (MASTER PIN) has been lost, please contact your service provider.

Preventing accidental activation

Even if PIN control is deactivated (p. 27) confirmation is required to switch on the phone.

This prevents accidental activation of the phone, e.g. when you are carrying it in a bag or travelling in an air- craft.
