Important Safety Instructions
The design and manufacture of the projector conforms to the most stringent safety requirements. Putting
the flammable material near the projector may cause the material to ignite itself, causing a fire. Once fire
occurs, be sure to use sand, CO2 or dry powder fire extinguishers. Do not use water to fire when an
electrical fire occurs.
It is advisable to leave a "quarantine" around all the outer surfaces of the projector. No flammable material
shall be placed in this area. Do not use any material to cover the projector or lens while the projector is
working.
Do not block the vents around the projector. Do not place paper or other objects in the range of 10 cm (4
inches) around the projector.
The slots on the projector are used for ventilation and heat dissipation. To ensure reliable operation of the
projector and to prevent it from overheating, do not block or cover these slots. The projector should not
be attached to walls or other similar surfaces to prevent clogging of these slots. The projector should not
be placed near the radiator or heat regulator. Unless the ventilation is good, the projector should not be
placed in the embedded device or enclosed device.
The projection room must be well ventilated or have a cooling device to avoid heat buildup. The hot air
discharged from the projector must be able to be discharged to the outside of the building.
If the projector is not used for a long period of time, remove the power cable.
Preventing fire
Do not service this equipment privately because opening or removing the cover may expose you to high
pressure and face an electric shock hazard.
If you attempt to change the internal control functions set at the factory or to change other control settings
that are not specifically addressed in this manual, it will cause permanent damage to the laser light source
suite and warranty failure.
When the following cases occur, unplug the device from the electrical outlet and allow qualified service
personnel to service:
- The power cable or power plug is damaged or worn.
- Liquid is splashed into the equipment.
- Equipment is in the rain or taking in water.
- If the device is not operating properly in accordance with the operation instructions, adjust only the
adjustment apparatuses mentioned in the operation instructions because improper adjustment of other
apparatuses may cause damage.
- The device falls to the ground or the case is damaged.
- If the equipment performance has changed significantly, ask the service personnel for help.
Replacement parts: When using replacement parts, ensure that the service technician uses approved
replacement parts or approved replacement parts that are identical to the original parts. Unauthorized
alternatives may result in deteriorated performance and stability, causing fire, electric shock, or other
hazards. Unapproved alternatives may void the warranty.
Safety check: When the projector is repaired, request the service technician to perform a safety check to
ensure that the device has returned to the normal operation state.
