Unpacking The Projector - Barco R90501001 User Manual

2. General
Which screen type ?
There are two major categories of screens used for projection equipment. Those used for front projected images and those for rear
projection applications.
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 (x 1) to a brushed aluminized screen with a gain of 10 (x 10)
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 projector is designed for projecting an image size : minimum 2 meter (6.6 ft.) to maximum 10 meter (32.8 ft.) (depending on
the ambient light conditions), with an aspect ratio of 4 to 3 .

Unpacking the projector

What has to be done ?
At delivery the projector is packed in a cardboard box upon a wooden pallet and secured with banding and fastening clips. Futher-
more, to provide protection during transport, the projector is surrounded with foam. Once the projector has arrived at the installation
site, it has to be removed from the cardboard box and wooden pallet in a safe manner without damaging the projector.
Necessary tools
Side cutter
How to unpack the projector
1. Remove the banding around the carton box, by releasing the fastening clips.
2. Cut open the box but do not insert the cutter too deep, otherwise the projector could be damaged.
