That Bell icon typically indicates that you have an alarm set on the BlackBerry. In order to make sure that the sounds are set properly for notifications you need to check the Profiles.
Go to Profiles > Advanced. Highlight the profile that shows "Active" next to it, then press the menu key and select Edit. Scroll to the event that shows Calendar, then press the trackball. Make sure the Out of Holster parameter is set to Tone, and that you have the appropriate Ring Tone selected. Also, make sure the volume is not set to Mute.
