8  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.
8.1 
OPTICS
The projection lens is mounted in the front of the projector. The optical
system is designed with a 8 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 above the projector 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!
8.2 
ILLUMINATION SYSTEM
The LCD projector uses a long life 575W metal halide lamp for
illumination. When approaching the end of the expected life time for the
lamp, a lamp timer will prompt for lamp change (see the Lamp
Replacement Messages section
). Each time the lamp is activated a
message stating software revision and used lamp life hours will appear in
the lower left hand corner of the screen.
The lamp is under high pressure when in operation. NEVER
attempt to open the unit for lamp change. Refer all servicing to
authorized personnel only. See the Lamp Replacement section.
