such as next to a heavy door. Follow these precautions to help prevent the image from becoming
misaligned:

excessively.
lMake 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.
lAdjust the projected image. See the included SMARTBoard 800i5e-SMP interactive
whiteboard system installation guide (smarttech.com/kb/157703) and Adjusting the image on
