Note: If two alarm conditions exist at the same time, the highest priority alarm is indicated. If two or 
more alarm conditions of equal priority exist at the same time, the most recent one will be displayed.
Note: The most recent alarms indicated by the device are logged for reference by service personnel. 
This log is maintained even if the device is powered down or if power is lost for any other reason.
Note: If the mute key is pressed prior to an alarm condition (for example, to mute the device in a 
movie theater), critical high priority and high priority alarms will override the mute function; medium 
and low priority alarms will be muted for eight hours from the time the key was pressed. Press the 
mute key off to display the last highest priority alarm. Press the mute key on again to reset the eight-
hour timer.
