Solving EasyManagement Problems 
You don’t see your projector in the EMP Monitor window.
■Make sure that you’ve connected the projector to the network and 
configured it correctly; see page 80. Also, make sure you’ve 
registered the projector with EMP Monitor; see page 81.
■Make sure that Standby Mode in the projector’s Extended menu 
is set to 
Network ON.
■If the computer you are using is running Windows XP or 2000, 
you must be logged in as the Administrator.
■Try restarting your computer.
Solving Problems with the Remote 
Control
The projector doesn’t respond to remote control commands.
■Be sure the ON/OFF switch is in the ON position, as shown on 
page 19.
■The remote control’s batteries may not be installed correctly or 
may be low on power. To change the batteries, see page 33. 
■Make sure your remote control’s ID is set to 0 or to the 
projector’s ID; see page 73.
■Make sure you are within about 33 feet (10 meters) of the 
projector and within range of the projector’s front or back sensor 
(approximately 20° to the left or right and 40° 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.

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 mounting, 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 13 for ordering information. You’ll also need to 
select 
Front/Ceiling or Rear/Ceiling as the Projection option of 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 75).
If 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.

							116Projector InstallationYou can correct the distortion using the 
Keystone function in the 
projector’s menu system (see page 65) or the keystone buttons on the 
projector’s control panel.
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.

Compatible Video Formats
The projector supports NTSC, PAL, and SECAM international video 
standards, as well as the monitor display formats listed below.
To project images output from a computer, the computer’s video card 
must be set at a refresh rate (vertical frequency) that’s compatible with 
the projector. Some images are automatically resized to display in the 
projector’s “native” format (XGA). The frequencies of some 
computers may not allow images to display correctly; see your 
computer’s documentation for details.
