Solutions When the Interactive Pens Do Not Work
If the interactive pens do not work, try the following solutions:
• The pens turn off automatically when not in use. Pick up the pen to turn it back on.
• Make sure PC Interactivity is set to On on the projector's interactive toolbar.
• Make sure you are not covering the black section near the tip of the pen.
• Make sure the pen tip is securely attached to the pen.
• Try replacing the soft pen tip with the hard pen tip.
• Make sure nothing is blocking the signal between the pen and the interactive pen receiver on the
projector.
• Try holding the pen at a different angle so that your hand is not blocking the signal.
• Make sure the cable cover is in place to keep cables from blocking the signal.
• Make sure the pen battery has enough power. Press the button on the side of the pen to check
remaining battery power. Try replacing the battery.
• If you are projecting from a computer, make sure the USB cable is connected to the computer and
projector.
• Dim the room lights and turn off any fluorescent lights. Make sure the projection surface and pen
receiver are not in direct sunlight or other sources of bright lighting.
• Remove any decorative lights from around the projector or projection surface.
• If the pen tip is worn out or damaged, you may need to replace it.
• Make sure the interactive pen receiver on the projector is clean and free from dust.
• Make sure there is no interference from infrared remote controls, mice, or infrared microphones.
