■The video signal may be split between the computer and the 
projector. If you notice a decline in the projected image quality 
when the image is displayed simultaneously on your notebook 
computer and the projector, turn off the notebook’s LCD display.

(see page 49).
The image is blurry.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 58.

to wait before using the projector after moving it from a cold 
environment to a warm environment.
■Adjust the Sharpness setting on the Image menu (see page 47). 
When you change video settings, you should be able to see the 
effect on the screen immediately. If you’re projecting from a

sync settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu, as described 
on page 48.

option in the projector’s Image menu to adjust the color (see 
page 46).

■Try adjusting the Volume setting in the Setting menu (see 
page 50).
■If you’re using a VCR or other video source, make sure the 
volume is not turned all the way down or muted. Also, make sure 
the cables are connected correctly, as described on page 40.
■If your presentation includes computer audio, make sure the 
volume control on your computer is not turned all the way down 
or muted. If you’re using the audio cable, make sure it is securely 
connected to both the projector and your computer’s 
headphone jack or   audio out jack.
■Make sure the Windows volume controls on your computer are 
not turned all the way down or set to Mute. You may be able to 
check this by clicking the volume control in your Windows 
system tray (lower right corner of the screen).
■Make sure the Mac volume controls are not turned all the way 
down. You may be able to adjust the volume from your menu bar 
(top right corner of the screen) or via the volume control function 
keys. 
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 26. 
■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.

A
Projector Installation
This appendix provides guidelines on installing the projector in a 
permanent location, such as a theater or conference room.
The projector can be installed for four different viewing setups: front 
projection, ceiling projection, rear projection onto a semi-transparent 
screen, or rear/ceiling projection, as shown: 
To project from overhead, you’ll need the optional ceiling mounting 
hardware; see page 11 for ordering information. You’ll also need to 
select 
Front/Ceiling or Rear/Ceiling as the Projection option in the 
projector’s Extended menu to flip the image upside-down. To project 
from the rear, onto a semi-transparent screen, select 
Rear or 
Rear/Ceiling (see page 56).
Front projectionRear projection
Rear/ceiling projectionCeiling  
						

							80Projector InstallationIf you’re mounting the projector on the ceiling and you place it above 
screen level, you’ll have to tilt the projector down to position the 
image on the screen. This causes the image to lose its square shape. 
You can correct the distortion using the 
Keystone function in the 
projector’s menu system (see page 49).
If you place the projector so that the base of the lens is level with the 
bottom of the screen, the image should be square and you won’t have 
to adjust it. If you place the lens lower than the bottom of the screen, 
you’ll have to tilt the projector upward if you want to fill the whole 
screen with the image.
