● Lock code (also known as security code) — The lock code helps you to protect your device against unauthorized use. The preset code is 12345. You can create and change the code, and set the device to request the code. Keep the new 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.

● UPUK code — This code (8 digits) is required to change a blocked UPIN code. If the code is not supplied with the USIM card, contact the network service provider whose USIM card is in your device.

● International Mobile Equipment Identity (IMEI) number — This number (15 or 17 digits) is used to identify valid devices on the GSM network. Devices that are, for example, stolen, can be blocked from accessing the network. The IMEI number for your device can be found under the battery.

Prolong battery life

Many features in your device increase the demand on battery power and reduce the battery life time. To save battery power, observe 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. Switch off Bluetooth 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. The WLAN on your Nokia device switches off when you are not trying to connect, not connected to another access point, or not scanning for available networks. To further reduce battery consumption, you can specify that your device not scan, or scans less often, for available networks in the background.

● If you have set Packet data connection to When available in connection settings, and there is no packet data coverage (GPRS), the device periodically tries to establish a GPRS connection. To prolong the operating time of your device, select Menu >

Tools > Settings and Connection > Packet data > Packet data connection > When needed .
