When an alarm setting is violated...

at the bottom of the screen. You can silence
the buzzer with the [CLEAR] key. (However,
the buzzer will sound whenever the alarm set-
ting is violated.) Press the [ALARM] key to
find out which alarm has been violated. The
offending alarm is displayed in red in the
ALARM INFORMATION window. Press the
soft key CLEAR ALARM to erase the alarm
indication. The alarm icon remains displayed
in red until all violated alarms have been ac-
knowledged.
