Bluetooth connectivity, and are not in hidden mode. Check
also that the distance between the two devices is not over
10 meters (33 feet) and that there are no walls or other
obstructions between the devices.

Q: Why can’t I end a Bluetooth connection?

A: If another device is connected to your device, you can

either end the connection using the other device or by
deactivating Bluetooth connectivity. Select

Display

Q: Why do missing, discolored, or bright dots appear on the

screen every time I turn 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.

Home network (UPnP)

Q Why can’t the other device see the files stored on my

device?

A: Make sure that you have configured the home network

settings,

Content sharing

is turned on in your device, and

the other device is UPnP compatible.

Q: What can I do if my home network connection stops

working?

A: Switch off the wireless LAN connection from your

compatible PC and your device, and switch it on again. If
this does not help, restart your compatible PC and your
device. If the connection still does not work, reconfigure
the WLAN settings in both your compatible PC and device.

Q: Why can't I see my compatible PC in my device in the home

network?

A: If you are using a firewall application in your compatible

PC, check that it allows home media server to use the
external connection (you can add Home media server to
the firewall application’s exceptions list). Check from the
firewall settings that the firewall application allows traffic
to the following ports: 1900, 49152, 49153, and 49154.
Some WLAN access point devices have a built-in firewall.
In such cases, check that the firewall in the access point
device does not block traffic to the following ports: 1900,
49152, 49153, and 49154.
Check that the WLAN settings are the same in your device
and compatible PC.

Memory low

Q: What can I do if my device memory is low?

A: You can delete unused items saved in your device regularly

to avoid memory getting low. See ‘Memory low—free
memory’, p. 68.
To delete contact information, calendar notes, call timers,
call cost timers, game scores, or any other data, go to the
respective application to remove the data. If you are
deleting multiple items and one of the following notes are
shown:

PC connectivity

Q: Why do I have problems in connecting the device to my PC?

A: Make sure that Nokia Nseries PC Suite is installed and

running on your PC. See the user guide for Nokia Nseries
PC Suite on the DVD-ROM. For further information on how
to use Nokia Nseries PC Suite, see the help function on
Nokia Nseries PC Suite or visit the support pages at
www.nokia.com.

Q: Can I use my device as a fax modem with a compatible PC?

A: You cannot use your device as a fax modem. However, with

call diverting (network service), you can divert incoming
fax calls to another phone number.

Wireless LAN

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 switch wireless LAN (WLAN) off on my Nokia

device?

A: The WLAN on your Nokia device will switch off when you

are not trying to connect, or are not connected to another
access point, or 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 will switch
off in between background scans.

To change the background scan settings:

1

Press

, and select

Tools

>

3

To save your changes, select

Back

.

When

Scan for networks

is set to

Never

, the WLAN

availability icon will not be shown in the standby mode.
However, you can still manually scan for available WLAN
networks, and connect to WLAN networks as usual.
