Temperature Log NOTES:
• If Manual Compartment Disable Mode has been activated during any of the indexes, average temperatures will
continue to be logged, but no event indicator will appear with these temperatures.
• If the unit was in Showroom Mode during any of the indexes, average temperatures will continue to be logged, but
no event indicator will appear with these temperatures.
• If the unit was switched OFF by touching the POWER key during any of the indexes and there was still power sup-
plied to the unit, the average temperatures will continue to be logged. This means temperatures would be expect-
ed to rise and the SERVICE indicator would be present in all indexes in which the unit was switched OFF.
• Temperature Log Recall Mode will end 20 seconds after the last key stroke.
