1. Introduction
Before Handling the Unit
• About the handling of this machine, follow the contents with reference to Safety Information in the
user manual.
Installation
The user must set this projector up.
Refer to the user's manual if related action is needed.
Precautions
Please follow all warnings, precautions and maintenance as recommended in this manual.
• This apparatus must be earthed.
• Do not look into the projector’s lens when the lamp is on. The bright light may hurt your eyes.
• To reduce the risk of fire or electric shock, do not expose this projector to rain or moisture.
• Do not open or disassemble the projector as this may cause electric shock.
• When replacing the lamp, allow unit to cool down at least 60 minutes, and follow all replacement
instructions.
• Do not use lens cap when projector is powered on.
• When the lamp reaches the end of its life, it will burn out and may make a loud popping sound. If
this happens, the projector will not turn back on until the lamp module has been replaced. To
replace the lamp, follow the procedures listed under “page 24 "Lamp Cover, Lamp Module"” in
“Part Replacement”.
10
Before Handling the Unit
• This product should be operated only from the type of power source which does not exceed the
voltage range specified on the rating label and the power cord.
• Do not use the polarized plug with an extension cord, receptacle, or other outlet unless the blades
can be inserted completely with three wire grounding type to prevent blade exposure. Failure to
follow these instructions may result in fire or electric shock.
• Plastic bags can be dangerous; please do not leave near babies and young children. To avoid the
threat of suffocation, please keep away from their nose and mouth.
• Do not ingest battery, Chemical Burn Hazard. Keep new and used batteries away from children. If
the battery compartment does not close securely, stop using the product and keep it away from
children. If you think batteries might have been swallowed or placed inside any part of the body,
seek immediate medical attention.
• Installing the Projector on a Wall or Ceiling:
1. Do not attempt to clean or replace parts for a machine that is installed in a high location on a
wall or ceiling. Doing so may cause it to fall down, resulting in an injury.
2. Do not open the lamp cover of a machine that is installed on a wall or ceiling. Doing so may
cause the lamp cover to fall down. If the lamp is broken, pieces of glass may fall and cause
an injury.
3. If a machine is incorrectly installed on a wall or ceiling, it may fall down and cause an injury.
4. Do not obstruct the machine's vents. Doing so risks fire caused by overheated internal
components.
5. Use brackets that are strong enough to support the projector. The projector weighs about 4.7
kg (10.36 lb.).
6. The projector must be installed in a location that is sturdy enough to support the full weight of
the projector and brackets.
7. Use only the screws (three M4×16 screws) provided with the projector to attach the brackets
to the projector.
8. Use all three of the projector's screw holes to attach the brackets. The locations of the screw
holes are shown in the illustration below. Make sure that the screws are tightened firmly.

never touch the unit, cables and/or peripherals. An electric surge caused by the storm, may result
in an electrical shock or damage to the unit.
• Never push objects of any kind into this product through openings as they may touch dangerous
voltage points or short-out parts that could result in a fire or electric shock. Never spill liquid of any
kind on the product.
• Do not place or keep the projector within the reach of the children. It may fall or tip over, possibly
causing serious injury.
• Do not stack other equipment on this product and do not place this product on other equipment.
