Aspect Ratio
The native display resolution of this projector is in a 16:9 aspect 
ratio. However, you may use this function to display projected 
picture in a different aspect ratio.
• Auto
Scales a picture proportionally to fit the projector’s native 
resolution in its horizontal or vertical width. This makes the 
most use of the screen and maintains the aspect ratio of a 
picture.
• 4:3
Scales a picture so that it is displayed in the center of the screen 
with a 4:3 aspect ratio.
• 16:9
Scales a picture so that it is displayed in the center of the screen 
with a 16:9 aspect ratio.
• Wide
Stretches a picture in a horizontal direction to fit the screen 
width. It does not alter the height of a picture.
• Letter Box
Scales a picture to fit the projector’s native resolution in its 
horizontal width and resizes the picture height to the 3/4 of the 
projection width. This makes a picture greater than the screen 
height. The top and bottom edges of the displayed picture are 
cropped. This suits the contents which are produced in letter 
box format (with black bars on the top and bottom).
Wall Color
Enable this function to help correct the projected picture’s color 
when the projection surface is not white. You may choose a 
color similar to that of the projection surface from these 
options: Light Yellow, Pink, Light Green, or Blue.
Image Position
Displays the Image Position window. You may use the 
directional arrow keys to adjust the position of the projected 
picture. 
The values shown on the lower position of the window change 
with every key press you made.
This function is only available when the PC signal is selected.
Overscan 
Adjustment
Conceals the poor picture quality in the four edges.
The greater the value, the more portion of the picture is 
concealed while the screen remains filled and geometrically 
accurate. Setting 0 means the picture is 100% displayed.

An on-screen display of the dialogue, narration, and sound 
effects of TV programs and videos that are closed captioned 
(usually marked as “CC” in TV listings).
• Caption Version
Select a preferred closed captioning mode. To view captions, 
select CC1, CC2, CC3, or CC4 (CC1 displays captions in the 
primary language in your area).
High Altitude 
Mode
The mode is for operation in areas like high altitude or high 
temperature environments. Activate the function when your 
environment is between 1500 m–3000 m above sea level and 
ambient temperature is between 0°C–30°C.
Do not use this function if your altitude is between 0 m and 
1500 m and ambient temperature is between 0°C and 35°C. If 
you turn on the mode under such a condition, the projector 
will be over cooled.
Operation under High Altitude Mode may cause a higher 
decibel operating noise level because of increased fan speed 
necessary to improve overall system cooling and performance.
If you use this projector under other extreme conditions 
excluding the above, it may display auto shut-down symptoms, 
which is designed to protect your projector from over-heating. 
In cases like this, you should switch to High Altitude Mode to 
solve these symptoms. However, this is not to state that this 
projector can operate under any and all harsh or extreme 
conditions.
Password
For security purposes and to prevent unauthorized use, you may 
set up password security for the projector. See Utilizing the 
password function on page 29 for details. 
• Change Password
You will be asked to enter the current password before changing 
to a new one.

Maintenance
Care of the projector
Your projector needs little maintenance. The only thing you need to do on a regular basis is 
to keep the lens clean.
Never remove any parts of the projector. Contact your dealer if other parts need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
• Use a canister of compressed air to remove dust. 
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens 
cleaner and gently wipe the lens surface.
• Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile 
solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or 
maintaining prolonged contact with rubber or vinyl materials may result in damage to 
the projector surface and cabinet material.
Never touch the lens with your finger or rub the lens with abrasive materials. Even paper towels 
can damage the lens coating. Only ever use a proper photographic lens brush, cloth, and cleaning 
solution. Do not attempt to clean the lens while the projector is switched on or is still hot from 
previous use.
Cleaning the projector case
Before you clean the case, turn the projector off using proper shutdown procedure as 
described in Shutting down the projector on page 28 and unplug the power cord.
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH 
detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the 
case.
Storing the projector
If you need to store the projector for an extended period of time, please follow the 
instructions below:
• Make sure the temperature and humidity of the storage area are within the 
recommended range for the projector. Please refer to Specifications on page 64 or 
consult your dealer about the range.
• Retract adjuster feet.
• Remove battery from the remote control.
• Pack the projector in its original packing or equivalent.
