Connecting to a Computer for Pen Use or USB Mouse Control

If you connected your computer to a Computer or HDMI port on the projector, you also need to connect
the USB cable so you can use the pens with your computer.
Connecting the USB cable also lets you set up the remote control to act as a wireless mouse, but you
cannot use this feature at the same time you are using the pens with your computer.
Note: You can connect your computer's USB cable to the control pad instead of directly to the projector.
