Solutions When the Interactive Pens are Slow or Difficult to Use
If the pens are difficult to use or respond too slowly, try the following solutions:
• For easier operation, hold the pen at an angle to the projection surface.
• For the best performance, connect your computer to the projector using an HDMI or VGA cable. Using
a USB cable to display your computer image (USB Display) may slow interactive pen function.
• Dim the room lights and turn off any fluorescent lights. Make sure the projection surface and
interactive module are not in direct sunlight or other sources of bright lighting.
• Make sure the receiver window on the interactive module is clean and free from dust.
• Make sure there is no interference from infrared devices such as infrared remote controls, infrared
microphones, and infrared mice.
• Make sure the location is free from electromagnetic interference from nearby equipment (such as
electric motors or transformers).
• Make sure you have calibrated the system. Try recalibrating.
