Power Fail
The POWER FAIL indicator light informs you that due to a power failure, the cabinet
temperature exceeded 23°F (-5°C). If the power failure lasted more than 1 hour, the
display alternates between showing the power failure duration (Hours and DURATION
LED illuminate in the display) and the cabinet temperature (°F or °C illuminates) every ½
second. This safety feature will aid in determining what food spoilage action to take.
