Unaligned projected image
Alignment errors occur when the projected image isn’t perpendicular to the screen. Alignment errors
can occur when you mount your interactive whiteboard system on an uneven surface or a wall that
has obstructions, or if you swivel the projector too far from the vertical center of your interactive
whiteboard.
Adjust the projected image. See the included SMARTBoard 800i6 interactive whiteboard system
installation guide (smarttech.com/kb/170TBA) and Adjusting the image on page 21.
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 800i6 interactive whiteboard
system installation guide (smarttech.com/kb/170TBA) and Adjusting the image on page 21.
