Troubleshooting 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 and Options > Settings > Multimedia message > Multimedia retrieval. Select 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 you have a new message 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 > Settings and Connectivity > Admin. settings > Packet data > Packet data connection > When needed. If this does not help, switch the device off and then on again. Q: Can I use my Nokia 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 a fax number. Q: How do I calibrate the screen? A: The screen is calibrated at the factory. If it is necessary to recalibrate the screen, select Menu > Settings and Phone > Touch input > Touch screen calibration. Follow the instructions. Q: Why do I get the error message Expired certificate or Certificate not valid yet when I am installing a downloaded application? A: If Expired certificate or Certificate not valid yet is displayed, even if the certificate should be valid, check that the current date and time in your device are correct. You may have skipped the setting of date and time when starting the device for the first time, or the mobile network may have failed to update these settings to your device. To resolve this, select Menu > Settings and Phone > Phone mgmt. > Factory settings. Restore the factory settings, and when the device restarts, set the correct date and time. © 2009 Nokia.
