alarm menu display. In the example below the bottom alarm has been violated.

2.  Press the C: 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 B: NEXT INFO soft key to see which other alarms have 
been violated. 

 The alarm icon is red when an alarm setting is violated, and changes to 

background color when the CLEAR key or C: CLEAR ALARM soft key is pressed. The 
color remains the same regardless of how many times another alarm is violated.
