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.
