6. Installation Guidelines
Screens are rated by how much light they reflect (or transmit in the case of rear projection systems) given a determined amount
of light projected toward them. The ‘GAIN’ of a screen is the term used. Front and rear screens are both rated in terms of gain.
The gain of screens range from a white matte screen with a gain of 1 (x1) to a brushed aluminized screen with a gain of 10 (x10)
or more. The choice 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.
What image size? How big should the image be?
The Cine VERSUM 80 is equipped with a Zoom Lens (1.80-2.44:1) designed for projecting images with screen size width of : min
0.60 m (2.36 ft) to max (6.10 m 24.02 ft) (depending on the ambient light conditions), with a default aspect ratio 16 : 9, electronic 4

The Cine VERSUM 120 can be combined with a wide versatility of lenses (optional) to project out-of-axis both horizontally and
vertically, which make the projector ideal for installation in the architecturally most demanding environment.

6.1.2.1 Cleaning the lens
To minimize the possibility of damaging the optical coating or scratching exposed lens surface, we have de-
veloped recommendations for cleaning the lens. FIRST, we recommend you try to remove any material from
the lens by blowing it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.
Necessary tools

TM
cloth (delivered together with the lens kit). Order number : R379058.
How to clean the lens ?
Proceed as follow :
1. Always wipe lenses with a CLEAN Toraysee
TM cloth.
2. Always wipe lenses in a single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.
Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Other lenses can also be cleaned safely with this Toraysee
TM
cloth.
