On preventing internal heat build-up
On cleaning
On repacking
After you turn off the power with the POWER key on the control panel or
the Remote Commander, do not press the MAIN POWER switch while the
cooling fan is still running.
Caution
The projector is equipped with ventilation holes (intake) at the bottom and
ventilation holes (exhaust) on the rear. Do not block or place anything near
these holes, or internal heat build-up may occur, causing picture
degradation or damage to the projector.
• To keep the cabinet looking new, periodically clean it with a soft cloth.
Stubborn stains may be removed with a cloth lightly dampened with a
mild detergent solution. Never use strong solvents, such as thinner,
benzene, or abrasive cleansers, since these will damage the cabinet.
• Avoid touching the lens. To remove dust on the lens, use a soft dry cloth.
Do not use a damp cloth, detergent solution, or thinner.
• Clean the filter at regular intervals.
• Save the original shipping carton and packing material; they will come in
handy if you ever have to ship your unit. For maximum protection,
repack your unit as it was originally packed at the factory.
