Codes
Chg.phonecode
You define and enter the phone
code (4-8 digits) when you call up a
phone-code protected function for
the first time (e.g. Babysitter p. 25).
It is then valid for all phone-code
protected functions.
Following the third unsuccessful at-
tempt, access to the phone code and
the functions that use it is denied. If
this happens please contact Siemens
Service (p. 124).
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 entry is deactivated (see
p. 17), confirmation is required to
switch on phone.
This prevents the phone from being
switched on accidentally, e. g. when
carried in a pocket or whilst you are
on an aircraft.
B
Hold down.
§OK§
Press. The phone
switches on.
§Cancel§
Press or take no action.

tion is broken off.
