5 Basic setup
5.1 Lens
5.1.1 Lens and lens mount
A range of fixed and zoom lenses is available to cover most applications, both both for front
and rear projection. The lenses are powered and fitted with a bayonet mount for ease of
installation.
Switch off all equipment before setting-up for proper function.
When mounting and changing lenses, be aware that the optical system is exposed to dust
and foreign particles as long as the lens is not attached to the system. Do not leave the lens
mount open longer than necessary to change lens. If a lens is not mounted, always insert the
protection lid to avoid dust and foreign particles entering the internal optics.
Never run the projector without lens mounted.
5.1.2 Inserting a lens
To insert a lens please follow this procedure:
A
Remove the protection lid from the bayonet mount by
turning the knob anti-clockwise.
B
Remove the rear lens cap.
C
Attach the projection lens using the bayonet mount,
observing the red insertion marks.
D
Turn the lens firmly clockwise until it stops with a click.
E
Remove the lens cap from the projection lens. If you
switch the projector on with the lens cap in place, the
lens cap may melt, damaging not only the lens cap,
but also the projection lens and surrounding parts.
5.1.3 Replacing a lens
To replace a lens please follow this procedure:
A
To change lens, first remove the current lens by
pushing the release button and twisting the lens
counter-clockwise until it comes loose. Pull the lens
out.
