About notification profiles
Notification profiles define how your BlackBerry® device notifies you of calendar and task
reminders, and incoming messages, calls, and browser content. Your device has six preloaded
profiles: Loud, Vibrate, Quiet, Normal, Phone Only, and Off.
You can change preloaded notification profiles or create new ones. In your notification profiles,
you can set different notification options for different items, set ring tones, or set the volume
for notification. If you set notification volume to Escalating, the notification volume gradually
increases.
