When the unit is exposed to such a change in temperature, moisture may condense on
the crucial internal parts. To prevent the unit from possible damage, do not use the unit for
at least 2 hours when there is an extreme or sudden change in temperature
.
Place and Manner of Installation•Do not place in hot locations, such as near heating equipment.  Doing so could cause
malfunction, and shorten the life of the projector.
•Avoid locations with oil or cigarette smoke.  Doing so will dirty the optical parts,
shortening their lives, and darkening the screen.
•Do not use the product vertically in any upright position or slantwise in an angle of 20
degrees or more.
•Using this instrument near a TV or radio may cause interference to the images or audio
sound. If this happens, move it away from the TV or radio.
•Moving the projector from a low-temperature room to a high-temperature room may
cause condensation on the lens or internal parts in the instrument. If you continue to use
it in that situation, the malfunction may result. Ensure to wait until the condensation
naturally disappears.
•In a high altitude location where air is thin, cooling efficiency is reduced so use it with the
ambient temperature being lowered.POWER SUPPLY CORD SELECTION
