							Introduction 8
Remote control effective range
Infra-Red (IR) remote control sensor is located 
on the front of the projector. The remote control 
must be held at an angle within 30 degrees 
perpendicular to the projectors IR remote 
control sensor to function correctly. The distance 
between the remote control and the sensor 
should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between 
the remote control and the IR sensor on the 
projector that might obstruct the infra-red beam.
Replacing the remote control battery
1. Pull out the battery holder.
Please follow the illustrated instructions. Push and 
hold the locking arm while pulling out the battery 
holder.
2. Insert the new battery (Type: CR-2025) in 
the holder. Note the positive polarity 
should face outward.
3. Push the holder into the remote control.
CAUTION
• Avoid excessive heat and humidity. 
• There may be battery damage if the battery is incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the battery manufacturer.
• Dispose of the used battery according to the battery manufacturer’s instructions.
• Never throw a battery into a fire. There may be danger of an explosion. 
• If the battery is dead or if you will not be using the remote control for a long time, remove 
the battery to prevent damage to the remote control from possible battery leakage.

							Positioning your projector 9
Positioning your projector
Choosing a location
Your room layout or personal preference will dictate which installation location you 
select. Take into consideration the size and position of your screen, the location of a 
suitable power outlet, as well as the location and distance between the projector 
and the rest of your equipment.
Your projector is designed to be installed in one of four possible installation 
locations:
1. Front Table
Select this location with the projector placed near 
the floor in front of the screen. This is the most 
common way to position the projector for quick 
setup and portability.
2. Front Ceiling
Select this location with the projector suspended 
upside-down from the ceiling in front of the screen.
Purchase the InFocus ceiling mount, SP-CEIL-
UNIV, from your dealer to mount your projector on 
the ceiling.
Set Front Ceiling in the SYSTEM SETUP: Basic > 
Projector Position menu after you turn the projector on.
3. Rear Table
Select this location with the projector placed near 
the floor behind the screen.
Note that a special rear projection screen is 
required.
Set Rear Table in the SYSTEM SETUP: Basic > 
Projector Position menu after you turn the 
projector on.
4. Rear Ceiling
Select this location with the projector suspended 
upside-down from the ceiling behind the screen.
Note that a special rear projection screen and the 
InFocus ceiling mount, SP-CEIL-UNIV, are required 
for this installation location.
Set Rear Ceiling in the SYSTEM SETUP: Basic > 
Projector Position menu after you turn the projector on. 
						

							Positioning your projector 10
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video 
format all factor into the resulting projected image size.
4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9 
(widescreen) aspect ratio image, the projector can resize and scale a widescreen 
image to the projectors native aspect width. This will result in a proportionally 
smaller height equivalent to 75% of the projectors native aspect height.
Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image 
displayed by this projector. This will be seen as darkened (unlit) bars along the top 
and bottom (vertical 12.5% height respectively) of the 4:3 projection display area 
whenever displaying a scaled 16:9 aspect image in the vertical center of the 4:3 
projection display area.
The projector should always be placed horizontally level (like flat on a table), and 
positioned directly perpendicular (90° right-angle square) to the horizontal center of 
the screen. This prevents image distortion caused by angled projections (or 
projecting onto angled surfaces). 
The modern digital projector does not project directly forward (like older style reel-
to-reel film projectors did). Instead, digital projectors are designed to project at a 
slightly upward angle above the horizontal plane of the projector. This is so that 
they can be readily placed on a table and will project forward and upwards onto a 
screen positioned so that the bottom edge of the screen is above the level of the 
table (and everyone in the room can see the screen).
If the projector is mounted on a ceiling, it must be mounted upside-down so that it 
projects at a slightly downward angle.
You can see from the diagram on page 12, that this type of projection causes the 
bottom edge of the projected image to be vertically offset from the horizontal plane 
of the projector. When ceiling mounted, this refers to the top edge of the projected 
image.
If the projector is positioned further away from the screen, the projected image size 
increases, and the vertical offset also increases proportionately.
When determining the position of the screen and projector, you will need to account 
for both the projected image size and the vertical offset dimension, which are 
directly proportional to the projection distance.
InFocus has provided a table of 4:3-aspect-ratio screen sizes to assist you in 
determining the ideal location for your projector. There are two dimensions to 
consider, the perpendicular horizontal distance from the center of the screen 
(projection distance), and the vertical offset height of the projector from the 
horizontal edge of the screen (offset).4:3 aspect image in a 4:3
