2	Install the downloaded USB driver on your computer.
	Read the instructions displayed on the download screen.
3	Change the "COM Port" setting in the "Extended"
	menu to "USB".
4	Turn the projector's power off.
5	Wait until the cool-downgperiod has ended and a
	"pip-pip" confirmation buzzer sounds, and then turn

on the power.

Once the projector's power has turned back on, communication via a USB Connection will then be possible.
