Nokia 6620 User Manual page 81

Avoid using security codes similar to emergency numbers, such as 911, to prevent
accidental dialing of the emergency number.
PIN code request—When the PIN code request is active, the code is requested each
time the phone is switched on. Note that deactivating the PIN code request may
not be allowed by some SIM cards.
PIN code (4 to 8 digits)—The PIN code protects your SIM card against unauthorized
use. The PIN code is usually supplied with the SIM card.
After three consecutive incorrect PIN code entries, the PIN code is blocked. If the
PIN code is blocked, you need to unblock the PIN code before you can use the SIM
card again. See also the information below about the PUK code.
PIN2 code (4 to 8 digits)—The PIN2 code is supplied with some SIM cards and is
required to access some functions, such as fixed dialing numbers (FDN).
Autolock period—You can set an autolock period, a time-out after which the
phone is automatically locked and can be used only if the correct lock code is
entered. Key in a number for the time-out in minutes, or select None to turn off
the autolock period.
To unlock the phone, key in the lock code.
When the phone is locked, calls may still be possible to the official emergency
number programmed into your phone.
Lock code (5 digits)—The lock code can be used to lock the phone and keypad to
avoid unauthorized use. The factory setting for the lock code is 12345. To prevent
unauthorized use of your phone, change the lock code. Keep the new code secret
and in a safe place separate from your phone. If you forget or lose the lock code,
contact your service provider.
Lock if SIM changed—Select Yes if you want the phone to ask for the lock code
when an unknown, new SIM card is inserted into your phone. The phone maintains
a list of SIM cards that are recognized as the owner's cards.
Fixed dialing—You can restrict your outgoing calls to selected phone numbers, if
supported by your SIM card. You need the PIN2 code for this function. When this
function is active, you can only call those phone numbers that are included in the
fixed dialing list or which begin with the same digits as a phone number on the list.
Press the joystick to set fixed dialing on. When fixed dialing is activated, calls still
may be possible to the official emergency number programmed into your phone. To
add new numbers to the fixed dialing list, select Options > New contact or Add
from Contacts.
Options in fixed dialing are Open, Call, Activ. fixed dialing or Deact. fixed dialing,
New contact, Edit, Delete, Add to Contacts, Add from Contacts, Find, Mark/Unmark,
Help, and Exit.
