When an alarm setting has been violated the buzzer sounds and the speaker icon appears
in red. Press the

changes from red to background color. You can see which alarm has been violated on the
alarm menu display. In the example below the bottom alarm has been violated.
To see which alarm(s) has been violated:
1. Press the
ALARM key. The name of the offending alarm is shown in the ALARM

2. Press the CLEAR ALARM soft key to acknowledge the alarm (and silence the buzzer if
it has not already been done with the CLEAR key). The color of the speaker icon
changes from red to background color. The icon remains on the screen until the reason
for the alarm is eliminated or the alarm is disabled. If more than one alarm has been
violated, the message CONTINUE appears at the bottom of the alarm information
window. In this case, press the NEXT INFO soft key to see which other alarms have
been violated.
Note: The alarm icon is red when an alarm setting is violated, and changes to
background color when the

color remains the same regardless of how many times another alarm is violated.
