The Orientation adjustment in the Set up menu allows you to
reverse the image vertically and horizontally (Fig. 9), to allow
the projector to be used for desktop front, ceiling front, desktop
rear and ceiling rear installations (Fig. 5).
To activate an electric motorised screen a TRig1 output is
provided at the rear of the projector (Fig. 6).
The output is activated (Voltage: 1V) when the projector is
switched on and is de-activated (no Voltage output) when the
projector is in stand-by mode.
You can also use black motorised curtains to delimit the screen
when the projected image aspect ratio changes (Fig. 7). This
option is controlled via the output TRig2 at the rear of the
projector.

For rear projection the screen must be translucent.
For front projection, we recommend the use of a screen with
black matt borders to contain the projected image.
Preferably use a unit gain screen; high gain screens are only
effective when used with a small group of viewers close to the
screen’s axis.
Prevent ambient light shining directly on the screen during
projection as this will reduce the contrast of the projected
image.
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.
