The pen doesn’t work.
Make sure nothing is blocking the signal between the pen and the
interactive pen receiver on the projector (see page 14).
Make sure the cable cover is in place to keep cables from blocking
the signal.
Make sure the pen batteries have enough power. If the light on
the pen doesn’t turn green when you press the button, you need
to replace the batteries.
If you are projecting through a wired or wireless network, make
sure the USB Type B option is set to Wireless Mouse in the
Extended menu (see page 78).
Dim the room lights and turn off any fluorescent lights. Make
sure the projection surface and the pen receiver are not in direct
sunlight or other sources of bright lighting.
Make sure the USB cable is securely connected to the projector
and computer. Try disconnecting and reconnecting the cable to
your computer.
The pen is hard to use.
For easier operation, hold the pen at an angle to the projection
surface.
The pen position is not accurate.
If you use the E-Zoom + button on the remote control to enlarge
the image, the pen position will not be accurate. When you return

Make sure the cable cover is in place to keep cables from blocking
the signal.
