Troubleshooting
(2) The ambient light may be too strong. Take the light out of
the site of the CMOS sensor.
Strong ambient light is usually caused by the following:
(2-1) Sunlight through the windows near the screen.
(2-2) Light source working close to the sensor or the screen.
Please quit the SP3 driver and execute again, if you see the
window shown as Question5. Please take the light out until you
can't see any light in Window.
3. Q: Why the cursor is not at the position that "Pointer" or
"Light Pen" pointed to?
A:
Possible reasons for this are:
(1) The system is not calibrated well. Try to point to the "center"
of circle target when you run calibration.(See Page 5~6 or
16~17 )
(2) The position of the projector, screen or projection size has
been changed.
(3) The image resolution has been changed.
Running the calibration procedure again will solve the
problem.
4. Q: Why is the cursor jumping?
A:
This may be caused by strong ambient light interference. Try
to avoid strong ambient light interference, especially strong
sun light directly projected on the screen. (Please refer to the
Question 2-2.)
The writing should be avoided in the
shadows.
Using Light pen to maintain 25° or
above with projection screen.
