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 perpendicular to the projector's IR remote control sensors to function correctly. The distance between the remote control and the sensors should not exceed 8 meters (~ 26 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.
Positioning your projector Choosing a location 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.
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. 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 projector's native aspect width. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect height.
How to determine the position of the projector for a given screen size 1. 2. Select your screen size. Refer to the table and find the closest match to your screen size in the left columns labelled "4:3 screen diagonal". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled "Recommended projection distance from screen in mm". This is the projection distance. 3.
