*1 When the screen changes to the initialization menu screen, if there were more than one NG factors, the error pop-up is
displayed according to the priority as described below.
(Such factors are all in the log internally but there is no way to show the log at present.)
Note that only the highest priority error pop-up is displayed. Therefore, if more than one-error factors have occurred at the
same time, it is necessary to correct one error factor at a time and restart.

For MacAddress NG:
For MemoryError:
For LowBattery:
When the screen changes to the initialization menu screen, the screen usually appears with Initialize All Memories item
selected but when Fader NG has occurred, the screen appears with Fader Calibration item selected.
