Security Settings; Changing Security Codes - NEC 535 Manual

Security Settings

The Security Settings allows the user to lock the handset to protect your phone from improper
use and prevent unauthorized users from accessing phone functions. The PIN codes, security
codes, and password codes are 4 to 8 digit numbers. While the handset is locked, you cannot
access any tools or information stored in the phone until the security code is correctly entered.

Changing Security Codes

PIN and PIN 2 codes are provided by your network service provider. The security code is user
defined and may be changed at any time. The default security code is '0000' until you change it.
Once the security code is changed, the default code is no longer valid.
PIN Code
Your phone can be set up so it needs your PIN code entered when powering on, before the
phone can be used at all. If the PIN code is not entered, received calls can not be answered. If
you input your PIN code incorrectly more than three times (not necessarily in the same session,)
the PIN code is invalidated and you will have to contact your service provider for a code to
unblock your SIM card.

PIN2 Code
Your phone supports advanced features (e.g. FDN--Fixed Dialing Number) that may require a
PIN 2 code to be entered before they can be accessed or modified. If you input your PIN 2 code
incorrectly more than three times (not necessarily in the same session), the PIN 2 code is
invalidated and you will have to contact your service provider for a code to unblock your SIM
card.

Press MENU (Main), 1, 7, 1, and 2 to display the PIN2 change screen.
Key in the current code. Press Softkey 1. You are prompted to input the new code, and
then to input it again as confirmation.

Some SIM cards are set
up so that PIN number
entry cannot be turned off.
SIM PIN Lock must be
enabled so you can
change the PIN code.
The PIN2 code is SIM
card related and may only
be available from your
service provider.
With FDN turned On, only
the FDN numbers in the
FDN Phonebook may be
dialed and called.
