(3) The projector turns power OFF.
The power can be turned OFF by the above exchange.
The power-OFF operation can be done by a sequence similar to that for power-ON.
The projector ignores data in the same state. For example, even if power-ON data is sent with the projector in power-ON mode,
no projector operation is done.
