Use the instructions in the included SMARTBoard 800i5e-SMP interactive whiteboard system
installation guide (smarttech.com/kb/157703) to eliminate most image alignment issues.
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
misaligned:
l Make sure that the installation wall is plumb and square and doesn’t move or vibrate
excessively.
l Make sure 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 Adjust the projected image. See the included SMARTBoard 800i5e-SMP interactive
whiteboard system installation guide (smarttech.com/kb/157703) and Adjusting the image on
page 33.
