Change phonecode

You define and enter the phone

code (4-8 digits) when calling up a

phone code protected function

(e.g. Babysitter, p. 17) for the first

time. It is then valid for all functions.

If you have forgotten it, please call

Siemens Service (p. 85).

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 together with

the SIM card according to instruc-

tions. If PUK (MASTER PIN) has been

lost, please contact your service pro-

vider.

Prevent accidental

activation

Even if PIN entry is deactivated (see

p. 10), confirmation is required to

switch on the phone.
This prevents accidental activation

of the phone, e.g. when you are car-

rying it in a bag or when you are trav-

elling in an aircraft.

Hold down.

§OK

phone.

§Cancel§
