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 to the original size, the pen position should be correct. ■ You may need to recalibrate (see page 49). ■ Make sure the cable cover is in place to keep cables from blocking the signal.
