Solutions When the Interactive Pens Do Not Work
If the pens do not work, try the following solutions:
• The pens turn off automatically if you forget to turn them off. Slide the switch to turn the pen back on.
• Make sure you are not covering the black section near the tip of the pen.
• 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 pen battery has enough 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.
• Do not place any type of decorative lights around the projector or projection surface.
• If the pen tip is worn out or damaged, you may need to replace it.
• Make sure the 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.
• Make sure the USB Type B option on the Extended menu is set to Easy Interactive Function or USB
Display/Easy Interactive Function .
• Make sure you have calibrated the system. Try recalibrating.
