Projector Placement Guidelines
To get the best results when projecting your images, it is 
important to 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:
Calculating Image Size and Projection 
Distance
The distance between the projector and the screen determines 
the 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 for the 
standard, long throw, and fixed wide angle lenses. (The size of 
the image can also be changed by rotating the zoom ring.)
Standard Lens Calculations
To determine the minimum and maximum diagonal size of an 
image when you know the projection distance:
oInches:
Maximum diagonal size = (0.6124 ´ projection distance) + 1.5264
Minimum diagonal size = (0.4556 ´ projection distance) + 1.1410
oCentimeters:
Maximum diagonal size = (0.6124 ´ projection distance) + 3.8771
Minimum diagonal size = (0.4556 ´ projection distance) + 2.8981
To determine the projection distance when you know the 
diagonal size of the screen image:
oInches:
Maximum projection distance = (2.1949 ´ diagonal size) - 2.5044
Minimum projection distance = (1.6328 ´ diagonal size) - 2.4923
oCentimeters:
Maximum projection distance = (2.1949 ´ diagonal size) - 6.3612
Minimum projection distance = (1.6328 ´ diagonal size) - 6.3304
For example, here are the measurements for three installations:
* For an image size of 300 inches, the projector may be up to 54 feet 
away from the screen, depending on the setting of the zoom ring. Input

If you are using the optional long throw zoom lens, use the 
following formulas.
To determine the minimum and maximum diagonal size of an 
image when you know the projection distance:

Minimum diagonal size = (0.2849 ´ projection distance) + 1.8968

Minimum diagonal size = (0.7236 ´ projection distance) + 4.8179
To determine the projection distance when you know the 
diagonal size of the screen image:

Fixed Wide Angle Lens Calculations
If you are using the optional fixed wide angle lens, use the 
following formulas.
To determine the minimum and maximum diagonal size of an 
image when you know the projection distance:
oInches:
Maximum diagonal size = (0.730 ´ projection distance) + 3.919
Minimum diagonal size = (0.616 ´ projection distance) + 3.050

Using the Remote Control  
The remote control uses a line-of-sight infrared signal. To use 
the remote control, point it towards one of the infrared  
receivers located at the front and back of 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 be within a 
± 30° 
angle from the front or rear receiver.
Note: The projector may not respond to remote control commands 
in these conditions: ambient light is too bright; a certain type of 
fluorescent light is present; a strong light source (such as direct 
sunlight) shines into the infrared receiver; or other equipment 
emitting infrared energy is present (such as a radiant room 
heater). Correct these conditions to use the remote control or 
control the projector from a computer.Open the cover just below the 
Esc button to access additional 
remote control commands.

Cleaning the Air Filter  
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.
2. Turn the projector on its side so that the handle is on top 
and you can access the filter easily.
Note: Standing the projector with the handle at the top keeps 
dust from getting inside the projector housing.
3. Pull the filter cover tab to release the filter cover. Remove the 
cover.
4. The filter is attached to the inside of the filter cover. It is 
recommended that you use a small vacuum cleaner designed 
for computers and other office equipment to clean the filter. 
If you don’t have one, use a dry, lint-free cloth.  
If the dirt is difficult to remove or the filter is torn, replace it.
5. Replace the filter cover when you’re done.
Replacing the Lamp   
The projection lamp typically lasts for about 1500 to 2000 
hours of use. It is time to replace the lamp when:
oThe projected image gets darker or starts to deteriorate.
oThe projection lamp indicator is either red, or flashing 
orange and red alternately. 
oThe message 
LAMP REPLACE appears on the screen when 
the projection lamp comes on. 
Warning:  Let the lamp cool before replacing it. Also, do not 
touch the glass portion of the lamp assembly. Touching the glass 
portion of the lamp will result in premature lamp failure.
1. Turn off the projector and unplug the power cable.
2. Turn the projector over so you can access the lamp cover.
3. Use a screwdriver, coin, or similar object to loosen the two 
retaining screws on the lamp cover. When the screws are 
loose, lift off the lamp cover. (You cannot remove these 
screws from the cover.
)
4. Use a screwdriver, coin, or similar object to loosen the two 
screws holding the lamp unit in position. (You cannot 
remove these screws completely.) 
5. Lift up the handle and pull out the lamp unit.
Enter Selects a menu option or the next menu/help screen. 
Pressing Enter when no menu or help screen is 
displayed optimizes the computer image.
Shift Pressing the shift and Keystone buttons at the same 
time increases or decreases the sound volume.
 – Keystone + Adjusts a trapezoid distorted image to normal.
 – Volume +
 Adjusts the volume when used in conjunction with the 
Shift button.
