If you encounter a problem with the interactive whiteboard, check all the cable connections. If this

Technical Support (page 33).
Calibrating the Cameras
Digital cameras in the corners of the interactive screen track objects such as your finger or a pen
tray pen. If the cameras become misaligned for any reason, you can experience “broken ink” (gaps
in your writing) or an area of the screen that’s unresponsive to touch.
Fortunately, you can realign the cameras by performing a simple calibration procedure, as
described below. If you think that you need to calibrate the DT770’s cameras, contact SMART
Technical Support (page 33).
