Knoll Systems HD225 user manual Positioning the projector

A 3.5mm mini-jack trigger provides 12- volt current. This provides a constant output while the projector is on. For example, if you connect your projection screen to the trigger, when you turn on the projector the screen will move down; when you turn the projector off, the screen will return to the storage position.

You must turn the trigger on in the

System menu, see page 21.

Positioning the projector

There are a number of factors to consider when determining where to set up the projector, including the size and

shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. Here are some general guidelines.

1 Position the projector on a flat surface at a right angle to the screen. The projector must be within 10 feet (3 m) of your power source. To ensure adequate cable access, place the projector at least six inches (0.15m) from a wall or other objects. Place the projector at least 5.6 feet (1.7 m) from the projection screen.

If you install the projector on the ceiling, refer to the installation guide that comes with the Ceiling Mount Kit for more information. To turn

the image upside down, see page 21. Knoll recommends use of an authorized Knoll ceiling mount. The Ceiling Mount Kit is sold separately.

2 Position the projector the desired distance from the screen.

The distance from the lens of the projector to the screen, the zoom setting, and the video format determines the size of the projected image. For more information about projected image sizes, see page 26.

The image exits the projector at a given angle. This image offset is 105%. This means that if you have an image 10’ high, the bottom of the image will be 0.5’ above the center of the lens.
