Troubleshooting
(Cont)
:
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.
3. Q: The cursor is not at
the same position as the
E-Pen/E-Wand is pointing:
Possible reasons for this are:
1
The system is not calibrated well.
Try to point to the “centre” of green
cross target when you run calibration.
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?
This may be caused by strong ambient
light interference. Try to avoid strong
ambient light interference, especially
strong sunlight directly projected on the
screen.
(Please refer to Question 2.)
5. Q: Why is the LightPen
not working after the
computer wakes up from
standby?
In some cases, if the computer goes
into standby mode, the computer will
shut the USB port. In such case, please
wake up computer, unplug and insert
the USB cable again.
(Please refer to
Question 1)
6.
Q:
There are ‘blank
spots’ where I am writing/
drawing with the E-Pen/
E-Wand:
1
Ensure your E-Pen/E-Wand is not
‘shadowed’ from line-of-sight with the
Projector
(see ‘Good Practice’ guidelines on
Page 07)
2
You may be writing/drawing over
an animated graphic (eg. animated gif/
flash file in a web page). In such cases
the computer sees this as redrawing
over the previous screen. Avoid
animated graphic areas when drawing/
writing with the E-Tools.
