The interactive pens are causing interference and unwanted effects. What should I do?

• If the pens are causing interference or unwanted effects, try the following solutions:

  • When you use two pens at the same time, make sure to use them at least 4 inches (10.16 cm) apart.
  • Do not rest the pens on the image area of an interactive table to avoid interference with your computer's mouse.
  • Make sure that nothing is blocking the direct line to the interactive pen receiver on the projector.
