2.General
the projected image falls together with the outline of the image in an On-Axis projection. Due to mechanical and optical
limitations it’s recommended to keep the shift values within the field of view (F) as illustrated below. Within these shift
ranges the projector and lens perform excellently. Configuring the projector outside these shift ranges will result in a slight
decline of image quality.

Field of view.
It is mechanical possible to shift outside the recommended field of view, but it will result in a decline of
image quality depending on the used lens and the zoom position of the used lens. Furthermore, shifting
too much in both directions will result in a blurred image corner.
Horizontal and vertical projector tilt ranges
Avoid to reduce the usage of lamp life. Suggest the projector rotated and mounted vertical angle not > ±15°.
Side to side tilt, however, must not exceed ±10°. This limit ensures that the lamp in the projector operates properly and safely.

2.5 Projector air inlets and outlets
Ventilation inlet:
The internal cooling fan draws cool air from the ventilation inlet into the projector.
Ventilation outlet:
The hot air generated inside the projector is dispersed through the ventilation slot. Make sure the ventilation slot is free from
