7. Do not place this projector in any of the 
following environments. 
- Space that is poorly ventilated or confined. 
Allow at least 50 cm clearance from walls 
and free flow of air around the projector. 
- Locations where temperatures may 
become excessively high, such as the 
inside of a car with all windows rolled up.
- Locations where excessive humidity, dust, 
or cigarette smoke may contaminate 
optical components, shortening the 
projector’s life span and darkening the 
image.
- Locations near fire alarms
- Locations with an ambient temperature 
above 40°C / 104°F
- Locations where the altitudes are higher 
than 10000 feet.
8. Do not block the ventilation holes. 
- Do not place this unit on a blanket, 
bedding or any other soft surface. 
- Do not cover this unit with a cloth or any 
other item. 
- Do not place inflammables near the 
projector.

Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the back of the projector. 
The remote control must be held at an angle within 30 degrees of the projector’s IR remote 
control sensors to function correctly. The distance between the remote control and the 
sensors should not exceed 6 meters (~ 20 feet). 
Make sure that there are no obstacles between the remote control and the IR sensors on the 
projector that might obstruct the infra-red beam.
Installing or replacing the remote control battery
• Avoid excessive heat and humidity. 
• There may be danger of damage to the remote and injury to those nearby if the battery is 
incorrectly replaced. 
• Replace only with the same or equivalent type recommended by the manufacturer. 
• Dispose of the used battery according to the 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 12
Positioning your projector
Choosing a location
Your projector is designed to be installed in one of two possible installation locations: 
1. Floor in front of screen; or
2. Floor at rear of screen
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.
Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format 
each factors in the projected image size.
The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 
aspect ratio (expressed as 4:3). 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 centre of the 4:3 projection display area.
When determining the position of your projector, you should consider its intended use and 
input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect 
I. Floor front: 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.
II. Floor rear: Select this location with the projector 
placed near the floor behind the screen.
Note that a special rear projection screen is 
required. Set  in the Advance > Mirror menu 
after you turn the projector on.
