hasbeen specifically designed for cleaning optical parts, never use industrial strength cleane rso n a projectors optics as these will

degrade optical coatings and damage sensitive optoelectronics.

Failureto take suitable precautions to protect the projector fro m the effects of persistent and prolonged air contaminants will culmi-

natein exte nsive and irreversible ingrained optical damage. At this stage cleaning of the internal optical units will be non-effective

andimpracticable. Damageof this nature is under no circumsta nces covered under the manufactures warranty and may deem the

warranty null and void. In such a case the client shall be held solely responsible for all costs incurred during any repair. It is the

clientsresponsibility to ensure at all times that theprojector is protected from the harmful effects of hostile airborne particles in the

environmentof the projector. Themanufacture reserves the right to refuse warranty repair if a projector has been subject to wantful

neglect, abandon or improper use.

Theambient light level of any room is made up of direct or indirect sunlight and the light fixtures in the room. T he amountofambient

lightwill determine how bright the image will appear. So,avoid direct light on the screen. Windowsthat face the screen should be

coveredby opaque drapery whilethe set is being viewed. Itis desirable to install the projection system in a room whose walls and

floorare of non-reflecting material. The use of recessed ceilinglights and a method of dimming those lights to an acceptable level

isalso important. Toomuch ambient light will ‘wash out’ of the projected image. This appears as less contrast between the darkest

andlightest parts of the image. Withbigger screens, the ‘wash out’ becomes more important. Asa general rule, darken the room to

thepoint where there is just sufficient light to read or write comfortably. Spotlighting is desirable for illuminating small areas so that

interference with the screen is minimal.

Thereare two major categories of screens used for projection equi pment. 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 o fga 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.

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

4to3.

Image retention can affect LCD projectors, in extreme cases, permanent “burn” can occur if still/repetitive images are left on the

screenfor long periods of time. Such damage to the panels is NOT covered by warranty.

Pleaseensure th atthe followingprecautions are taken to avoid this phenomenon :

1. Use a screensaver (that moves)

2. Periodically change/alterany backgroundimages on the desktop

3. Turnoff the projector when not in use.
