ChangePhonecode

You define and enter the phone

code (4 - 8 digits) when calling a

phone code protected function

(e.g. babysitter, p. 20) for the first

time. It is then valid for all protected

functions.
If it is entered incorrectly three times

the phone is locked. Contact the Sie-

mens Service (p. 92).

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, according to instructions. If the

PUK (MASTER PIN) has been lost,

please contact your service provider.

Prevent accidental

activation

Even if PIN use is deactivated (p. 12)

confirmation is required to switch on

rying it in a bag or when you are trav-

elling in an aircraft.
