(Change phone code)

You define the phone code (4 to

8digits) when you call up a phone- code protected function for the first time (e.g. Direct call, page 27). It is then valid for all phone-code pro- tected functions.

Following the third unsuccessful at- tempt, access to the phone code and the functions that use it is denied. If this occurs, contact Siemens Service (page 128).

Preventing accidental activation

Even if PIN control is deactivated (page 17) 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 when you are travelling in an aircraft.

Clear SIM card barring

by your service provider with the SIM card in accordance with the in- structions. If the PUK (MASTER PIN) has been lost, please contact your service provider.
