3. Wait until you see a flashing green circle in the upper left corner of your
projected image.
4. Touch the center of the circle with the tip of the pen. The circle stops flashing
and turns black. You see another circle on the right.
5. Touch the center of the next circle, then repeat. When you get to the end of
the row, the next circle appears at the left edge of a new row.
Note: For the most accurate calibration, make sure you
hold the pen at an angle to the projection surface and
touch the center of the circle.
Make sure you are not blocking the signal between the pen
and the interactive receiver (next to the projection window)
on the projector.
Don't press the button on the side of the pen while calibrating.
If you make a mistake or want to stop calibrating, press Esc on your computer
keyboard. Then restart the calibration process as described above.
6. Continue until all of the circles are black.
After you have finished calibration, you can use the pen as a mouse on the
projection board or wall. With additional software, you can also use the pen to
write or draw on the projected image. You can use any annotation software you
have or Easy Interactive Tools, as described on page 17.
