get the eyesight hurt. This is especially the case with children.
●Unplug the AC power plug if the projector will not be used for long time.
●DO NOT overload the socket of power cord as it may lead to re or electric shock. DO
NOT subject the power cord to any object. DO NOT place the projector in locations
where its power cord may become damaged by treading by passersby.
●Disconnect the power plug before cleaning the projector. DO NOT apply liquid or sprays
to the projector. DO NOT wipe the projector with wet cloth.
●Please follow warnings and instructions given in labels attached to the projector. Unplug the
projector when the projector is exposed to thunderstorm weather, is unmanned, or
not in use for long periods to prevent damage caused by lightning and power surges.
●DO NOT use accessories without recommendation by the manufacturer as it may result in
potential risks.
Caution
Precautions on air outlet:
●Keep adequate clearance around the projector for its ventilation and cooling. See gure be-
low for the least clearance requirements. The least clearance is a MUST when the projector
is placed within a cabinet or other closed environment.
Sides and bottom Rear
●DO NOT cover the air outlet of the projector. Poor ventilation not only shorten life cycle of
the projector but also may lead to risks.
●Slots and openings at rear and bottom of the projector are designed for ventilation. Keep the
projector from overheated to ensure its steady operation.
●DO NOT cover the air outlet with cloth or other objects. DO NOT place the projector on the
surface of bed, sofa, carpets, or similar object as this may block the air outlets at its bottom.
●DO NOT place the projector in closed environment, e.g. a bookcase, unless it is well venti-
lated.
● Keep any matter from falling in the projector through the air outlets as they may touch high
voltage parts and lead to re or electric shock by short circuits. DO NOT splash liquid to the
projector.
