projector came with an orange pen (Interactive Pen A), identified
by the color on the end of the pen. If you want to use dual pen
interactivity and annotation, you will need to purchase the
optional blue pen (Interactive Pen B). You can use
either pen, or both at the same time (one of each color).
Make sure the pen batteries are installed.
Note: The pens
turn off automatically after 20 minutes of inactivity. Slide the
switch to turn the pen back on.
