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 infrared site on
the projector.
- Turn off
hovering.
