SXGA LCD PROJECTOR

New sources are added to the memory only if the sync pattern differs
significantly from a previous selection. If a new source is detected as an
old one (close or identical sync patterns), and the settings are changed,
the new settings will override the old ones.

COOLING SYSTEM
The heat generated in the projection lamp and in the electronics circuitry
needs to be effectively vented out of the projector. Cooling fans are
employed to force the convection of air through the system. Air is let out
close to the projection lamp (as this is the hottest area).

The projector is designed to operate at a wide temperature range and
works well when ceiling mounted, even at high ambients. See the technical
Data section for temperature specification.

Data section for temperature specification.
The cooling system is temperature controlled, so that when operated on
the desktop at normal temperature, the noise level is minimized due to a
relaxed fan speed. When operating in the ceiling under high temperature
ambients, the fan runs at a higher speed to maintain cooling while the
noise level increases.
