neglect, abandon or improper use.

What about ambient light ?

Theambient light level of any room is made up of direct or indirect sunlight and the light fixtures in the room. T he amount ofa mbient
lightwill determine how bright the image will appear. So,avoid direct light on the screen. Windows that face the screen should be
coveredby opaque drapery whilethe set is being viewed. It is desirable to install the projection system in a room whose walls and
floorare of non-reflecting material. Theuse of recessed ceiling lights and a method of dimming those lights to an acceptable level
isalso important. Toomuch ambient light will ‘wash out’ ofthe projected image. Thisappears as less contrast between the darkest
andlightest parts of the image. Withbigger screens, the ‘wash out’ becomes more important. As a general rule, darken theroom to
thepoint where there is just sufficient light to read or write comfortably. Spot lighting is desirable for illuminating small areas so that
interference with the screen is minimal.

Which screen type ?

Thereare two major categories of screens used for projectionequipment. Those used for front projected images and those for rear
projectionapplications. Screensare rated by how much light they reflect (or transmit in the case of rear projection systems) given a
determinedamount of light projected toward the m. The ‘GAIN’ of a screen is the term used. Front and rear screens are both rated
interms of ga in. The gain of screens range from a white matte screen with a gain of 1 (x1) to a brushed aluminized screen with a
gainof 10 (x10) or more. Thechoice between higher and lower gain screens is largely a matter of personal preference and another
consideration called the Viewing angle. In considering the type of screen to choose, determine where the viewers will be located
and go for the highest gain screen possible. A high gain screen will provide a brighter picture but reduce the viewing angle. For
more information about screens, contact your local screen supplier.

Image size

Theprojector is designed for projecting an image size with a screenwidth from 1.00m (3.3ft) to 6.00m (19.7ft) with an aspect ratio of
16 to 9.
