Troubleshooting
1. Q: Why does it show “No LightPen
found”?
Reasons for this might be:
1
The USB cable is not properly connected.
Check cable connections at computer and
Pro-Vue Projector.
Should the Lightpen icon appear with a red cross
in your Toolbar, the USB cable may have been
disconnected at computer/projector. Check
connections are correct and secure.
*
Some Anti-virus programs will disable the USB
port. Please make sure the USB port is not
disabled.
2
Please check if the USB port of the PC supports
USB 2.0 or not.
3
You may have the wrong USB cable. Ensure to
use the cable supplied with your Pro-Vue Projector.
Should you require a longer lead, please contact
your dealer.
4
USB port on computer malfunctions. Please check
if the USB port is functioning correctly. If not,
please consult with IT engineer.
Some notebook computers will disable USB ports
when the battery is low. Please use AC power whenever
possible. Some notebook computers do not provide
standard 500mA to the USB port or the USB converter
is not working properly. In such case, please use our
standard USB cable.
2. Q: Why can I not execute calibration
on the green cross target?
Please check E-Pen/E-Wand are functioning:
1.1
Please check if E-Pen/E-Wand batteries or battery
cap is loose.
1.2
When using E-Pen or E-Wand, be sure to locate
the tip in the sight of the CMOS sensor in front of
the projector. If the sensor cannot see it, the
Interactive system does not work.
2
The ambient light may be too strong. Take the
light out of the sight 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.
3
In Windows Vista system, one of the green cross
targets may be hidden by “start” square of
computer/notebook computer. Please point to the
position as shown for calibration.
