Note
When abnormalities are detected by the state of DC power supply and
USB bus power supply, it will be in this state. Opening display is not
performed, either, when abnormalities are detected at the time of starting.
When update goes wrong and FLASH-ROM is not written correctly,
it will be in this state. Even in this case, update can be performed
succeedingly. However, "3" is displayed while it can be communicating
neither with the case where USB cable is not connected, nor USB
controller, correctly also at this time.
When the time when it cannot communicate with USB controller
correctly although USB cable is connected at the time of starting, and
controllers are abnormalities, it will be in this state.
When the time when it cannot communicate with a needle pad
controller correctly, and controllers are abnormalities, it will be in this
state. However, this display is performed at the time of "[1] Check of
operator input and a display function." It will be used in usual use, with
a needle pad not operating.
