Important points concerning the installation

Please read the following carefully before the installation of this unit.

Installation environment

CAUTION

This unit is a precision device. Therefore, please refrain from installation or use in the following locations. Otherwise, it may cause fire or malfunction.

•Dust, wet and humid locations.

•Sooty or cigarette smoke filled locations.

•On top of a carpet or bedding, or other soft surfaces.

•Locations with high temperatures - as located in direct sunlight.

•Locations with high or low temperatures.

Permissible operating temperature range: +5 º to +35º .

Relative humidity range permissible for operating: 20% ~ 80% (non-condensing) .

Storage temperature tolerance: -10ºto +60º.

•If the installation of the unit is done in a room with soot and/or smoke over a longer period, even small amounts of these substances will affect the device.This unit cools its optical components, which produce a great amount of heat, by sucking in air. If the optical circuits get dirty, this might lead to malfunctions, like the video images becoming darker or a deterioration of the color development. Dirt sticking to the optical components cannot be removed.

Please be careful to perform the installation at a certain

CAUTION distance from walls and other devices

For better heat dissipation, please keep a minimum distance between this unit and its surroundings as shown in the following illustration.

Moreover, please open the front of the unit. If there are any objects in front of the exhaust port, the hot air will flow back to the unit and heat it. The hot air flowing out of the unit might cause shadows on the screen (heat haze phenomenon).

Moreover, when it is enclosed in a space as shown in the following illustration, please make sure that the enclosed interior has the same temperature as the outside. High temperatures might lead to failure of the unit.

Please be careful when using

CAUTION

This unit uses a projection lamp, which will get hot when in use. Please refrain from projecting in the following circumstances.

Otherwise, it might cause fire or malfunction.

•Projection while lying on its side.

Please avoid projection if the installation of the unit is done at an excessive angle of more than ± 30 °. It may cause harm to the life of the lamp and color shading.

•Please avoid projection at a location where the air vents or exhaust ports might get blocked.

Please choose a non-uniform cloth material for the screen. If you choose something uniform, like something with a checkered pattern, there might be interference with the pixel array of the D-ILA components. One way to reduce the interference pattern is to change the size of the screen, so that it will not be so noticeable.
