Solutions When the Interactive Pens are Slow or Difficult to Use
If the pens are difficult to use or respond too slowly, try the following solutions:
°
For easier operation, hold the pen at an angle to the projection surface.

interactive module are not in direct sunlight or other sources of bright lighting.

Make sure the receiver window on the interactive module is clean and free from dust.
°
Make sure there is no interference from infrared devices such as infrared remote controls, infrared
microphones, and infrared mice.

Make sure the location is free from electromagnetic interference from nearby equipment (such as
electric motors or transformers).
