Deterioration Check
It is recommended to do the deterioration check (Refresh) regularly to check the LD
status.
When the detected output is 90% or less of the that before shipping (Factory initial),
error No.045/FC-LD POWER DOWN occurs. Press the TROUBLE RESET button to
clear the error.
Check the PEAK POWER setting and prepare the FC-LD for replacement when the
value is lower than the deterioration rate shown below. It doesn't mean that the FC-
LD immediately reaches the end of its useful life even when error No.045/FC-LD
POWER DOWN occurs.
