Warning: If you install a software update, you cannot use the device, even
to make emergency calls, until the installation is completed and the device is
restarted. Be sure to back up data before accepting installation of an update.
Downloading software updates may involve the transmission of large amounts of
data (network service).
Make sure that the device battery has enough power, or connect the charger before

Select from the following:
● PIN code request  — When active, the code is requested each time the device
is switched on. Deactivating the PIN code request may not be allowed by some
SIM cards.
● PIN code andPIN2 code — Change the PIN and PIN2 code. These codes can only
include numbers. Avoid using access codes similar to the emergency numbers to
prevent accidental dialling of the emergency number. If you forget the PIN or
PIN2 code, contact your service provider. If you forget the lock code, contact a
Nokia Care point or your service provider.
● Lock code  — The lock code is used to unlock the device. To avoid unauthorised
use of your device, change the lock code. The preset code is 12345. The new code
can be 4-255 characters long. Alphanumeric characters and both uppercase and
lowercase characters can be used. The device notifies you if the lock code is not
properly formatted. Keep the new code secret and separate from your device.
● Phone autolock period  — To avoid unauthorised use, you can set a time-out
after which the device automatically locks. A locked device cannot be used until
the correct lock code is entered. To turn off autolock, select None.
