Same here I was concerned about that as well at first. If your worried, set an alarm for yourself in five minutes, put it to silent, and see if it rings for yourself. That's how I figured it out.
Not quite sure what a full power off is, but if the device is turned off (via the power/end call key) the device will still turn on and ring at the scheduled alarm time.
Using the quiet mode at night and it still allows the alarm to ring - which is desired.
However, REMINDERS also go off (ie: All day events, which if reminder is set will go off at midnight) . . . - which is not desired. Is there some setting I'm missing for this?
Thanks for any help.
Yep, bigbank. You can go into Profiles and select Quiet.
Then go into Profiles and select Advanced and Edit and find the setting for Calendar. Change that to NONE and it should stay silent and stop flashing a light in your face while you are trying to sleep.
