The pen position is not accurate. What should I do?

• Try the following:
  • If you use the E-Zoom + button on the remote control to enlarge the image, the pen position will not be accurate. When you return to the original size, the pen position should be correct.
  • You may need to recalibrate. See Calibrating the Projector.
  • Make sure the cable cover is in place to keep cables from blocking the signal.
