your computer and the number of hours the lamp has been used. 
Press the 
Menu button and highlight the Info menu.

pattern to appear as your desktop background, or try 
projecting black text on a white background.
2. Adjust the 
Tracking to eliminate vertical bands. 
3. Adjust the 
Sync setting to increase the image sharpness. 
The image is too light or dark, or colors are incorrect.

Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 28. 
■Make sure you are within about 20 feet (6 meters) of the projector 
and within range of the projector’s front or back sensor 
(approximately 30° to the left or right and 15° above or below).
■Dim the room lights and turn off any fluorescent lights. Make 
sure the projector is not in direct sunlight. Strong lighting, 
especially fluorescent lights, may affect the projector’s infrared 
receivers. Also, turn off any nearby equipment that emits infrared 
energy, such as a radiant room heater.
