4.12.6 When an alarm setting is violated...
When an alarm setting has been violated the buzzer sounds and the speaker
icon appears in red. Press the [CLEAR] key to silence the alarm. At this time the
color of the speaker icon 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

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 [CLEAR] key or CLEAR ALARM soft key
is pressed. The color remains the same regardless of how many times
another alarm is violated.
3. Press the [ALARM] key to close the menu.
