If possible, reposition the projector so that it is
centered on the screen and below the bottom of the
screen.
•
Press the Keystone correction keys on the control
panel or remote control until the image becomes
square.

Press "MENU" on the control panel or remote
control to open the OSD menu. Go to "Image" >
"Auto Keystone" or "Image" > "Manual Keystone"
to make adjustments.
•
Select "Image" > "Projection Mode", "Image" >
"Projection Location" on the OSD and adjust the

Ensure the video source cable is connected properly,
and that the video source is turned on.

Make sure that the control panel lock
function is disabled.
When the lamp reaches the end of its useful

popping sound. If this happens, the projector
will not turn on until the lamp module has
been replaced. To replace the lamp, contact
your local dealer or Acer service center.
