6 USING THE LCD PROJECTOR
The LCD projector has a set of connectors and controls that you need to
know in order to operate the device correctly.
6.1 OPTICS
The projection lens is mounted in the front of the projector. The optical
system is designed with a 12 degree keystone correction so that the
projected image is shifted upwards on the wall. This in effect enables the
placement of the projector on a flat table, still getting a rectangularly
projected image on the wall.
Avoid scratching and bumping the lens, as this will reduce the
quality of the projected image. Always re-cap the lens when not
in use!
6.2 ILLUMINATION SYSTEM
The LCD projector uses a 400W halogen lamp for illumination. An
additional lamp (spare lamp) is included in case the main lamp goes out.
The two lamps are mounted in a motorized lamp changer. If one lamp
fails, the other lamp can be shifted in place for continuous operation by
pressing the LAMP CHANGER button on the control panel.
Always replace a defective lamp with a new one after the
projector has cooled down, since the internal lamp house is hot
when in use.
