Troubleshooting
To see frequently asked questions about your device, visit the product
support pages at the Nokia web site.
Q: What is my lock, PIN, or PUK code?
A: The default lock code is 12345. If you forget or lose the lock code, contact
your device dealer. If you forget or lose a PIN or PUK code, or if you have not
received such a code, contact your network service provider.
Q: How do I close an application that is not responding?
A: Press and hold the home key. Scroll to the application, 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.
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 the 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 end a Bluetooth connection?
A: If another device is connected to your device, you can end the connection
using the other device or by deactivating Bluetooth connectivity. Select
Menu > Connectivity > Bluetooth > Bluetooth > Off.
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.
To stop the background scans, select Menu > Tools > Settings >
Connection > Wireless LAN > Show WLAN availability > Never. You
can still manually scan for available WLAN networks and connect to WLAN
networks as usual.
To increase the background scan interval, select Show WLAN
availability > Yes, and define the interval in Scan for networks.
Q: Why can't I browse the web even though the WLAN connection is
working and the IP settings are correct?
A: Check that you have defined the HTTP/ HTTPS proxy settings correctly in
the advanced settings of your WLAN access point.
Q: How do I check the signal quality of my WLAN connection?
Select Menu > Connectivity
> Conn. mgr. > Active data
connections > Options > Details. If the signal quality is weak or
moderate, you may encounter connection problems. Try again closer to the
access point.
Q: Why do I have problems with the security mode?
A: Check that you have configured the security mode correctly, and that it is
the same that the network uses. To check the security mode the network
uses, select Menu > Connectivity > Conn. mgr. > Active data
connections > Options > Details.
Check also the following: you have the correct WPA mode (preshared key or
EAP), you have disabled all EAP types that are not needed, and all the EAP
type settings are correct (passwords, user names, certificates).
Q: Why can’t I select a contact for my message?
A: The contact card does not have a phone number, an address, or an e-mail
address. Select Menu > Contacts, and edit the contact card.
Q: The note Retrieving message is shown briefly. What is happening?
A: The device is trying to retrieve a multimedia message from the multimedia
messaging centre. This note is shown if you have set Multimedia
retrieval to Always automatic in the multimedia message settings. Check
that the settings for multimedia messaging are defined correctly and that
there are no mistakes in phone numbers or addresses.
See "Multimedia
message settings," p. 22.
Q: How can I end the data connection when the device starts a data
connection again and again?
A: The device may be trying to retrieve a multimedia message from the
multimedia message centre. To stop the device from making a data
connection, select Menu > Messaging > Options > Settings >
Multimedia message > Multimedia retrieval > Manual to have the
multimedia messaging centre save messages to be retrieved later, or Off to
ignore all incoming multimedia messages. If you select Manual, you receive
a notification when there is a new multimedia message that you can retrieve
in the multimedia message centre. If you select Off, the device does not make
any network connections related to multimedia messaging.
To set the device to use a packet data connection only if you start an
application or action that needs it, select Menu > Tools > Settings >
Connection > Packet data > Packet data connection > When
needed.
If this does not help, switch the device off, and switch it on again.
Q: Why do I have problems connecting the device to my PC?
A: Ensure that you have the latest version of Nokia PC Suite and that it is
installed and running on your compatible PC. For further information on how
to use Nokia PC Suite, see the help function on Nokia PC Suite or visit the
support pages of the Nokia web site.
Q: How do I save battery power?
A: Many features in your device increase the demand on battery power and
reduce the battery life time. To save battery power, do the following:
Switch off Bluetooth when you do not need it.
Stop the background scans for WLAN. Select Menu > Tools > Settings >
Connection > Wireless LAN > Show WLAN availability > Never. You
can still manually scan for available WLAN networks and connect to WLAN
networks as usual.
Set the device to use a packet data connection only if you start an
application or action that needs it. Select Menu > Tools > Settings >
Connection > Packet data >
Packet data connection > When
needed.
Prevent the device from automatically downloading new maps in the
Maps application. Select Menu > Tools > Maps > Options >
Settings > Network > Use network > Off.
Change the time-out after which the backlight is switched off. Select
Menu > Tools > Settings > General > Personalisation > Display >
Light time-out.
Close the applications you do not use. Press and hold the home key. Scroll
to the application, and press the backspace key to close the application.
