Light Interference: Light omitting objects (ex. decorative lights, digital clocks, etc.) can interfere with the signal from the projector to the whiteboard reducing or eliminating interactive functions.
Object Interference: Placing objects such as magnets or decorations on or near the whiteboard surface can interfere with performance. Please keep the surface cleared from objects.
If the projected video is playing at an unusually fast speed and the audio is distorted, please restart both your projector and computer. Once both devices have been restarted, the video should resume normal playback.
