If you are having trouble calibrating, try the
following solutions:
-
Try
restarting the Easy Interactive Driver.
-
If the
flashing circles don’t appear when you try to calibrate, make sure
the USB cable from the interactive module is securely connected to
the computer.
-
If the
circles don't stop flashing and don't turn black (or they stop
flashing and turn black automatically), dim or turn off any bright
lights near the projection surface.
