To view frequently asked questions about your device, see the product support
pages at www.nokia.com/support.
Q: What is my password for the lock, PIN, or PUK codes?
A: The default lock code is 12345. If you forget the lock code, contact your device
dealer. If you forget a PIN or PUK code, or if you have not received such a code,
contact your network service provider.
For information about passwords, contact your access point provider, for example,
a commercial internet service provider (ISP) or network service provider.
Q: How do I close an application that is not responding?
A: Press and hold the menu key.
Q: Why do images look smudgy?
A: Ensure that the camera lens protection windows are clean.
Q: Why do missing, discoloured, or bright dots appear on the screen every
time I switch on my device?
A: This is a characteristic of this type of display. Some displays may contain pixels
or dots that remain on or off. This is normal, not a fault.

Q: Why can’t I find my friend’s device while using Bluetooth connectivity?
A: Check that both devices are compatible, have activated Bluetooth connectivity,
and are not in hidden mode. Check also that the distance between the two devices
is not over 10 metres (33 feet) and that there are no walls or other obstructions
between the devices.

Q: Why can't I see a wireless LAN (WLAN) access point even though I know I'm
within its range?
A: The WLAN access point may use a hidden service set identifier (SSID). You can
only access networks that use a hidden SSID if you know the correct SSID, and have
created a WLAN internet access point for the network on your Nokia device.
Q: How do I turn the wireless LAN (WLAN) off on my Nokia device?
A: The WLAN on your Nokia device turns off when you are not connected or trying
to connect to another access point, or not scanning for available networks. To
further reduce battery consumption, you can specify that your Nokia device does
not scan, or scans less often, for available networks in the background. The WLAN
turns off in between background scans.
To change the background scan settings, do the following:
