User Guide > Find help

The in-device user guide is stored in the internal mass memory of your device. When you install system software updates, the information in the user guide may not be up to date. To view the latest user guide, go to the support pages at www.nokia.com/support.

When you want to learn more about how to use your product or you are unsure how your device should function, go to www.nokia.com/support, or using a cellular phone, www.nokia.mobi/support, or, in your device, select > User Guide.

• Restart the device: switch off the device, and remove the battery. After about a minute, replace the battery, and switch on the device.

• Restore the original factory settings.

• Update your device software.

If your issue remains unsolved, contact Nokia for repair options. Go to www.nokia.com/repair, or in Latin America, www.nokia-latinoamerica.com/centrosdeservicio. Before sending your device for repair, always back up the data in your device.

Your device normally has GPRS, streaming, and mobile internet settings automatically configured, based on your network service provider. You may have settings from your network service provider already installed in your device.

To change the general settings in your device, such as language, desktop, display, and keypad lock settings, go to > Settings.

If you forget any of the access codes, contact your service provider.

• Personal identification number (PIN) code - Protect your device and SIM card against unauthorized use. The PIN code (4-8 digits) is usually supplied with the SIM card. After three consecutive incorrect PIN code entries, the code is blocked, and you need the PUK code to unblock it.
• Personal Unblocking Key (PUK) code - This code (8 digits) is required to change a blocked PIN code. If the code is not supplied with the SIM card, contact your service provider.
• Lock 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 lock code and your device is locked, you must take the device to a Nokia authorized service facility and additional charges may apply. To unlock the device, the software must be reloaded, and all data you have saved in the device, may be lost.

Many features in your device increase the demand on battery power and reduce the battery life time. To save battery power, observe the following:

• Switch off Bluetooth when you do not need it. Applications that use Bluetooth technology should be closed when not needed.

• 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 device scans available networks as often as specified in WLAN settings and connects automatically to the networks that have been used before. To further reduce battery consumption, you can specify that your device not scan, or scans less often, for available networks in the background.

• The backlight of the display increases the demand on battery power. In the display settings, you can adjust the display brightness and change the length of the time-out period, after which the backlight switches off. You can also activate the power saving mode to set the device to consume less power when the display backlight is on. To edit display settings, select > Settings and Display.

• Leaving applications running in the background increases the demand on battery power.
