Alarms
The chest freezer alarm system is shown below. When an alarm is active, a
message appears in the LED message center. Press the Mute key to silence
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.
All alarm delays and ringback times are +30 seconds.
*The automatic battery test runs immediately on start-up, then every 8 hours thereafter.
