logged. No event indicator will appear with these temperatures.
• If the unit was switched OFF by pressing the POWER key during any of the 168 indexes and there was still power
supplied to the control board, the average temperatures will continue to be logged. This means temperatures
would be expected to rise and the SERVICE icon would be present in all indexes in which the unit was OFF.
