Cooling System - Ask Proxima Impression A6+ User Manual

USER GUIDE XGA LCD PROJECTOR
The memory can store up to 40 different sources and mode characteristics.
Some sources are predefined, while the remaining are available for
customer set-up. See the compatibility list in the Technical Data section.
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.
See the Remote Control and Menu sections for details of which functions
that are memorized.

10.9 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.
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. The light leakage out of the vents is minimized by a special
light blocking design of the vent flanges.
