Figure 3-54. Bell Illuminates - Indicates Power Failure / Interruption During that Index Period
NOTE: If the unit was in Showroom Mode during any of the 168 indexes, average temperatures will continue to be
logged. No event indicator will appear with these temperatures.
NOTE: If the unit was switched OFF by pressing the UNIT ON/OFF 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 tem-
peratures would be expected to rise and the SERVICE icon would be present in all indexes in which the unit was
OFF.
NOTE: Temperature Log Recall Mode will end 20 seconds after the last key stroke.
