z500a Ring/Vibrate/Mute Schedule??

I've read the z500a manual online and I still want to know for sure if this phone has a feature where one can tell it at what times you want it to ring or vibrate or be mute. I know from past experience that I forget to tell it to ring at times like lunch or after school, and I would like to be able to recieve as many calls as possible without having to constantly change its status.

Press that button to go to main menu, Go to Organizer, than Alarms.

Not an alarm, I want to have a schedule of when it should ring, vibrate or be mute when someone calls.
