The Orientation adjustment in the Set up menu will allow the
projector to be used for desktop front, ceiling front, desktop
rear and ceiling rear installations (Fig. 10) .
To activate an electric motorised screen a 12 Volt output is
provided at the rear of the projector or with the optional Remo-
te Input Interface. This can be connected to a screen interface
unit, which can be supplied by screen manufacturers (Fig. 11) .

The output is activated (Voltage: 12 Vdc) when the projector is
switched on and is de-activated (no Voltage output) when the
projector is in stand-by mode.
For rear projection the screen must be translucent.
For front projection, we recommend the use of screens with
low gain specifications (i.e. 1.3 to 2). The use of high gain
screens should be avoided due to their limited viewing angle,
which is undesirable for a large audience.
Preferably, use a screen with black, non-reflecting borders,
which will perfectly frame the projected image.
Avoid light shining directly on the screen during projection as
this will reduce contrast and black level detail on the projected
image. For the true cinema experience best results are
achieved with little or no ambient light.
Furniture and other objects with reflecting surfaces, as well as
light coloured walls should be avoided, as they are likely to
interfere with the screen's characteristics.
