Safety information
• If an extension cord is necessary, a cord with a current rating at least equal to that of the projector should
be used. A cord rated for less amperage than the projector may overheat.
• Never push objects of any kind into this product through cabinet slots as they may touch dangerous
voltage points or short out parts that could result in a risk of fire or electrical shock.
• Make sure that no objects enter into the vents and openings of the set.
• Do not expose this projector to rain or moisture.
• The projector is designed for indoor use only. Never operate the unit outdoors.
• Do not immerse or expose this projector in water or other liquids.
• Do not spill liquid of any kind on this projector.
• Should any liquid or solid object fall into the cabinet, unplug the set and have it checked by qualified
service personnel before resuming operations.
• Do not disassemble this projector, always take it to qualified service personnel when service or repair work
is required.
• Do not use an accessory attachment which is not recommended by the manufacturer.
• Lightning - For added protection for this video product during a lightning storm, or when it is left unattended
and unused for long periods of time, unplug it from the wall outlet. This will prevent damage to the device
due to lightning and AC power-line surges.
To prevent personal injury
• To prevent injury and physical damage, always read this manual and all labels on the system before
powering the projector or adjusting the projector.
• To prevent injury, take note of the weight of the projector. The weight of a basic projector is about 48 kg
(105 lb) without lens.
• To prevent injury, ensure that the lens and all covers are correctly installed. See installation procedures.
• Warning: high intensity light beam. NEVER look into the lens ! High luminance could result in damage to
the eye.
• Warning: extremely high brightness projector: This projector embeds extremely high brightness
(radiance) lasers; this laser light is processed through the projectors optical path. Native laser light is not
accessible by the end user in any use case. The light exiting the projection lens has been diffused within
the optical path, representing a larger source and lower radiance value than native laser light.
Nevertheless the projected light represents a significant risk for the human eye when exposed directly
within the beam. This risk is not specific related to the characteristics of laser light but solely to the high
thermal induced energy of the light source; which is comparable with lamp based systems.
Thermal retinal eye injury is possible when exposed within the Hazard Distance. The Hazard Distance
(HD) is defined from the projection lens surface towards the position of the projected beam where the
irradiance equals the maximum permissible exposure as described in the chapter "High Brightness
precautions: Hazard Distance", page 16.
• High Brightness Warning: The projector light source may not be switched on or the shutter must be closed
when no projection lens is installed.
• Based on international requirements, no person is allowed to enter the projected beam within the zone
between the projection lens and the related Hazard Distance (HD). This shall be physically impossible by
creating sufficient separation height or by placing optional barriers. Within the restricted area operator
training is considered sufficient. The applicable separation heights are discussed in "High Brightness
precautions: Hazard Distance", page 16.
• Warning: Laser radiation when optional laser distance meter is installed. Do not stare into laser ranging
beam. Class 2 laser beam could result in damage to the eye.
• Don't put your hand in front of the beam.
• This product contains no user serviceable parts. Attempts to modify/replace mechanics or electronics
inside the housing or compartments will violate any warranties and may be hazardous. This kind of
operations shall only be performed by Barco authorized service personnel.
• Before attempting to remove any of the projector's covers, you must turn off the projector and disconnect
from the wall outlet.
• When required to switch off the projector, to access parts inside, always disconnect the power cord from
the power net.
• The power input at the projector side is considered as the disconnect device. When required to
switch off the projector, to access parts inside, always disconnect the power cord at the projector
side. In case the power input at the projector side is not accessible (e.g. ceiling mount), the socket
outlet supplying the projector shall be installed nearby the projector and be easily accessible, or a
readily accessible general disconnect device shall be incorporated in the fixed wiring.
• Do not stack or hang projectors without using the stacking frame.
