Installation Position - WolfVision VZ-C12 Bedienungsanleitung

INSTALLATION POSITION

A difference between Ceiling- and "Desktop-"Visualizers is that the size of the smallest and largest
image the unit can pick up is not fixed. This depends on how high above the working surface the
Visualizer is mounted. It is very important to know which image sizes you would like to pick up
with the Ceiling Visualizer before installing the unit, in order to decide in which distance to the
working surface the Ceiling Visualizer will be mounted to the ceiling.
The relationship between the mounting height and image sizes can be checked with the calculation
program on WolfVision's homepage (see below).

A very comfortable method to calculate the exact
positioning and the possible image sizes is a
dedicated calculation program on WolfVision's
homepage:

In extremely high rooms the smallest image
the unit can pick-up may not be small enough.
In such cases a standard ceiling mount or
projector-lift can be used to suspend the
Ceiling Visualizer further from the ceiling.
