Setting Alarms
You can set two types of alarms, which perform different actions when
they come due:
■ Appoiiitinent alarm. This displays the message you specified when
you set the alarm. It also sounds a sequence of beeps for about 15
seconds—or until you press a key. You’re expected to acknowledge
an appointment alarm after it comes due.
■ Control alarm. This executes the program or other object you
specified when you set the alarm—no other action occurs. You don’t
acknowledge a control alarm.
When you set an alarm, it’s saved in the system alarm list, where it
can be reviewed and edited (“browsed”) later.
