Alarms
The Revco CxF freezer alarm system is shown below. When an alarm is
active, a message appears in the LED message center. Press the Silence key
to mute the audible alarm for the ringback period. The visual alarm
continues until the freezer returns to a normal condition. The alarms are
momentary alarms only. If an alarm condition occurs and then returns to
normal, the freezer automatically clears the alarm condition and the
message center.
