in your device, or you may receive or request the settings
from the network service providers as a special message.
You can change the general settings in your device, such
as language, standby mode, display, and keypad lock
settings.
Access codes
PIN or PIN2
code
(4-8 digits)
These protect your SIM card against
unauthorised use or are required to access
some features.
You can set your device to ask for the PIN
code when you switch it on.
If not supplied with your SIM card or you
forget the codes, contact your service
provider.
If you enter the code incorrectly three
times in a row, you need to unblock the
code with the PUK or PUK2 code.
PUK or PUK2
code
(8 digits)
These are required to unblock a PIN or
PIN2 code.
If not supplied with your SIM card, contact
your service provider.
IMEI number
(15 digits)
This is used to identify valid devices in the
network. The number can also be used to
block, for example, stolen devices.
To view your IMEI number, dial *#06#.
Lock code
(security
code)
This helps you protect your device against
unauthorised use.
(min. 4 digits
or
characters)
You can set your device to ask for the lock
code that you define.
Keep the code secret and in a safe place,
separate from your device.
If you forget the code and your device is
locked, your device will require service.
Additional charges may apply, and all the
personal data in your device may be
deleted.
For more information, contact a Nokia
Care Point or your device dealer.
Prolong battery life
Many features in your device increase the demand on
battery power and reduce the battery lifetime. To save
battery power, note the following:
• Features that use Bluetooth technology, or allowing
such features to run in the background while using
other features, increase the demand on battery power.
Deactivate Bluetooth technology when you do not need
it.
• Features that use wireless LAN (WLAN), or allowing such
features to run in the background while using other
features, increase the demand on battery power. WLAN
on your Nokia device deactivates when you are not
trying to connect, not connected to an access point, or
not scanning for available networks. To further reduce
battery consumption, you can specify that your device
does not scan, or scans less often, for available
networks in the background.
