on. Refer to the computer manual.
If the image is out of focus:
Be sure the lens cap is open.
While displaying the on-screen menu, adjust the focus ring. (The image size should not

Press the
AUTO PC
button.
Press the

Remote control problems
If the remote control does not operate:
Be sure nothing is blocking the remote control receiver on the front or back of the projector.
Use the remote control within the effective range.
Aim the remote control at the screen or at the front or back of the projector.
Move the remote control so it is more directly in front of or behind the projector and not as far
to the side.
The battery could be weak. Replace with a new battery.
