The front projector looks complicated with all the wires laying around, but once you know how to turn it on, you'll see it's pretty simple. Just do the following steps.

1. Pull down the projector screen on front wall.
2. Connect the HDMI cable near the vertical post into your laptop/macbook.
3. Point remote to the projector and press the “On” button (blue button).
4. Once you see the projector come on and show the instruction screen, press the red button (Standby) which will look for valid inputs and will switch to your device.
