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.
