NOTE1:
A PD record representing 5 blinks of the Red LED (a PD of the
power-supply section) must display "0000 NONE", accumulated
time and temperature together. If only "0000 NONE" is displayed,
but the accumulated time and temperature are zero, it means
there was no PD.
If "0000 NONE"is displayed and the internal thermal sensor temp-
erature is 78°C or more, it represents a record of a shutdown
(SD) prompted by the abnormal temperature (indicated by 4 blinks
of the Green LED), and not a record of a PD of the power-supply
section.
