The built-in toolbar (PC Free Annotation) does not work. What should I do?

• If you cannot use the pen without a computer, try the following solutions:
  • Press one of the Source buttons on the remote control to select the source for the image you want to annotate. To use a blank screen, select Computer2 or another unused source.
  • Make sure you have calibrated the system. Try recalibrating.
  • Press the Pen Mode button on the remote control to toggle between PC Interactive and PC Free Annotation modes.
