Blackberry 8300 Cell Phone User Manual

Date and time troubleshooting
The time on my device is incorrect
Try performing the following actions:
If you have traveled to a different time zone, set the Time Zone field to display the correct time zone.
If you have set the Date/Time Source field to Network, try setting the Date/Time Source field to BlackBerry.
Notification profile troubleshooting
My device is vibrating more times than expected
For calls, the number of times that the BlackBerry® device vibrates is not determined by the number of vibrations that you set in your
notification profile. The device vibrates until the caller or the wireless network ends the connection.
I am not receiving notification for incoming calls or messages
Try performing the following actions:
In the profile list, verify that the Off profile is turned off.
In a notification profile exception, verify that the Custom Phone Tune field is not set to Mute.
I cannot set some fields when creating a Calls From notification profile exception
If you assign a custom ring tone to a contact in the address book, a Calls From profile exception appears in the profile list. Because these
exceptions are for calls only, you can only set the Custom Phone Tune field.
Display troubleshooting
My device screen turns off
When you do not use your BlackBerry® device for a period of time, the screen turns off to conserve battery power.
To turn on the screen, click the trackball or press a key.
My display changed
Depending on your theme, display options, such as your font and Home screen background, might change when you switch themes.
