phone with a hot or cold battery may
temporarily not work, even when the
battery is fully charged.

Access Codes
The access codes described in this section
help you protect against unauthorised use
of your phone and SIM card.
When asked for any of the access codes,
key in the proper code and press OK. If you
make a mistake, first delete the digit with
Clear and then key in the correct one.
For changing the codes, see page 49.
N
OTE: Avoid using access codes similar to
emergency numbers, such as 112, to pre-
vent accidental dialling of the emergency
number.
Security code
The security code is supplied with the
phone. It protects your phone against un-
authorised use. Keep the code secret and
in a safe place, separate from the phone.
See also ”Security level (Menu 4-5-5)” on
page 49.
If you key in an incorrect security code five
times in succession, the phone will not ac-
cept the correct code for the next five
minutes.
PIN code
The PIN (Personal Identity Number) code is
usually supplied with the SIM card. It pro-
tects your SIM card against unauthorised
use.
When the PIN code request is enabled (see
page 46), the code is asked each time the
phone is switched on.
If you enter a wrong PIN code three times
in succession, key in the PUK code and
press OK. Key in a new PIN code and press
OK. Key in the new code again and press
OK.
PIN2 code
The PIN2 code, supplied with some SIM
cards, is required to access some func-
tions, such as charging unit counters.
These functions must be supported by
your SIM card.
If you enter a wrong PIN2 code three
times in succession, follow the same in-
structions as for the PIN code but this
time using the PUK2 code.
