Projector Placement Guidelines
To get the best results when projecting your images, position
the projector at the proper height and distance relative to the
screen. When projecting from a table or desk, place the
projector so the lens is aligned as closely as possible with the
bottom of your screen:
When projecting from the ceiling, align the lens as closely as
possible with the top of your screen:
The distance between the projector and the screen determines
the actual image size. To determine the exact distance required
for a particular image size (or to determine the size of an image
at a particular distance), use the following formulas.
(Remember that the size of the image can be changed by
rotating the zoom ring.)
To determine the minimum and maximum diagonal size of an
image when you know the projection distance:
❏ Inches:
Maximum image size = (0.6038 × projection distance) + 1.8898
×
Minimum image size = (0.4631
❏ Centimeters:
Maximum image size = (0.6038 × projection distance) + 4.8001
Minimum image size = (0.4631
To determine the projection distance when you know the
diagonal size of the screen image:
❏ Inches:
Maximum projection distance = (2.1593 × image size) – 3.0229
Minimum projection distance = (1.6562
❏ Centimeters:
Maximum projection distance = (2.1593 × image size) – 7.6782
Minimum projection distance = (1.6562
projection distance) + 1.4000

Using the Remote Control
The remote control uses a line-of-sight infrared signal. To use
the remote control, point it toward the infrared receiver
located at the front of the projector.
To be able to use the remote control as a cordless mouse,
connect the projector to your computer with the mouse cable
(PS/2 or ADB-Macintosh) that came with the projector.
You can use the remote control up to about 32.8 feet
(10 meters) from the projector. (This distance may be shorter
if the remote control batteries are low.) You must also hold the
remote control so that it is within
± 15° higher or lower than, the infrared receiver.

Note: If the projector doesn’t respond to remote control
commands, a strong light source (such as direct sunlight) may be
hitting the infrared receiver. The presence of a certain type of
fluorescent light or equipment emitting infrared energy (such as a
radiant room heater) can also interfere with the transmission of
remote commands.

Cleaning the Air Filter
overhea ting.
sensor.
Clean the air filter at the bottom of the projector after every
100 hours of use. If it is not cleaned periodically, it can
become clogged with dust, preventing proper ventilation. This
can cause overheating and damage the projector. To clean the
air filter, follow these steps:
1. Turn off the projector and unplug the power cable from the
electrical outlet.
2. Place the projector on its side with the handle at the top so
that the filter is easily accessible.
Note: Placing the projector in this position keeps dust from
getting inside the projector housing.
3. Lift up the tab securing the air filter cover and remove the
cover. (The air filter is attached to the inside of the cover.)
4. Use a small vacuum cleaner designed for computers or other
office equipment to clean the filter. If you don’t have one,
use a dry, lint-free cloth.
If the dirt is hard to remove or if the filter is torn, replace the
air filter.
Note: An air filter comes with each replacement lamp (part
number ELPLP07).
5. Replace the air filter cover.
6. Plug the power cable back into the electrical outlet.
Replacing the Lamp
The projector lamp typically lasts for about 2000 hours of use.
It is time to replace the lamp when:
The projected image gets darker or starts to deteriorate
❏
The projector lamp light is flashing orange and red
❏
alternately
The message LAMP REPLACE appears on the screen when
❏
the projector lamp comes on
Warning: Let the lamp cool before replacing it. Also, don’t touch
the glass portion of the lamp assembly; this can cause premature
lamp failure.
1. Turn off the projector and unplug the power cord from the
electrical outlet and the projector. Wait at least 20 minutes
for the bulb to cool.
2. Place the projector on its side with the handle on the top so
you can easily access the lamp cover.
Note: Placing the projector in this position keeps dust from
getting inside the projector housing.
3. Use a screwdriver, coin, or similar object to loosen the
retaining screw on the lamp cover. When the screw is loose,
lift off the lamp cover. (You cannot remove this screw from
the cover.)

Caution: Don’t touch the glass portion of the lamp assembly;
this can cause premature lamp failure.
5. Lift up the handle and pull out the lamp assembly.
6. Gently insert the new lamp assembly by sliding it into
position. Make sure it’s inserted securely. Tighten the screws
on the new lamp assembly.
7. Replace the lamp cover and tighten the cover screw. (Make
sure the lamp cover is securely fastened. The projector won’t
run if the lamp cover is open.)
