Also, just because you've entered an event in your calendar, it doesn't mean you'll actually remember to attend it.

To help ensure you won't miss an important conference call (or Little League game), when entering a new appointment, scroll down to the Reminder field to set an alarm to remind you of the appointment.

You can use the left and right joystick controls to choose how far in advance of the appointment you want the alarm to go off—anywhere from one minute before to one week ahead of time.
