contact your network service provider.

responding?

and press the backspace key to close the application.
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.

Bluetooth connectivity?
A: Check that both devices are compatible, have activated
Bluetooth connectivity, and are not in the hidden mode.

deactivating Bluetooth connectivity. Select

Q: Why can't I see a WLAN access point even though I
know I'm within its range?
A: Check that the Offline profile is not in use in your device.
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 access point for the network on your Nokia device
Check that the WLAN access point is not on channels 12-13,
as they cannot be associated with.
Q: How do I switch WLAN off on my Nokia device?
A: 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
Nokia device does not scan, or scans less often, for
available networks in the background. WLAN switches off
in between background scans.
