The projector image can slip if the projector is moved often or installed in a location prone to vibration,
such as next to a heavy door. Follow these precautions to help prevent the image from becoming
unaligned:
l
Ensure that the installation wall is plumb and square and doesn’t move or vibrate excessively.
l
Ensure that there are no obstructions behind the projector’s wall-mounting bracket and that the
bracket is firmly secured to the wall according to the installation instructions.
l
Ensure that the projection surface is flat and smooth.
