723–0018 /02 F7016
3.1 To prevent the risk of electrical shock
Electrical Shock
•This product should be operated from a mono phase AC power source.
•This apparatus must be grounded (earthed) via the supplied 3 conductor AC power cable. If none of the
supplied power cables are the correct one, consult your dealer. If you are unable to insert the plug into the
outlet, contact your electrician to replace your obsolete outlet. Do not defeat the purpose of the grounding-
type plug.
•Do not allow anything to rest on the power cord. Do not locate this product where persons will walk on the
cord. To disconnect the cord, pull it out by the plug. Never pull the cord itself.
•Use only the power cord supplied with your device. While appearing to be similar, other power cords have
not been safety tested at the factory and may not be used to power the device. For a replacement power
cord, contact your dealer.
•Do not operate the projector with a damaged cord. Replace the cord. Do not operate the projector if the
projector has been dropped or damaged - until it has been examined and approved for operation by a
qualified service technician.
•Position the cord so that it will not be tripped over, pulled, or contact hot surfaces.
•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 opening 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 an authorized trained service person when service or
repair work is required.
•Do not use an accessory attachment which is not recommended by the manufacturer.

effective UV radiation. An evaluation of the workplace is advised to assure employees are not exposed to
cumulative radiation levels exceeding these government guidelines.
3.3 To prevent fire hazard
Fire Hazard
•Barco projection products are designed and manufactured to meet the most stringent safety regulations.
This projector radiates heat on its external surfaces and from ventilation ducts during normal operation,
which is both normal and safe. Exposing flammable or combustible materials into close proximity of this
projector could result in the spontaneous ignition of that material, resulting in a fire. For this reason, it is
absolutely necessary to leave an “exclusion zone”around all external surfaces of the projector whereby no
flammable or combustible materials are present. The exclusion zone in the exhaust area must be not less
than 100 cm (40”). The exclusion zone on the intake area must not be less than 50 cm (20”). The exclusion
zone on the lens side within the light beam must be at least 1,5 m.
•Do not place flammable or combustible materials near the projector!
•Slots and openings in this equipment are provided for ventilation. To ensure reliable operation of the
projector and to protect it from overheating, these openings must not be blocked or covered.
•.The openings should never be blocked by placing the projector too close to walls, or other similar surface.
Allow for sufficient distance to walls and ceilings to avoid overheating. Minimum safety distance to the
exhaust area of the unit must not be less than 100 cm (40”) and to the intake area, not less than 50 cm
(20”).
•This projector should never be placed near or over a radiator or heat register.
•This projector should not be placed in a built-in installation or enclosure unless proper ventilation is
provided.
•Do not cover the projector or the lens with any material while the projector is in operation. Keep flammable
and combustible materials away from the projector at all times.
•Mount the projector in a well-ventilated area away from sources of ignition and out of direct sun light.
•Never expose the projector to rain or moisture. In the event of fire, use sand, CO2 or dry powder fire
extinguishers.
•Never use water on an electrical fire.
•Always have service performed on this projector by authorized Barco service personnel. Always insist on
genuine Barco re- placement parts. Never use non-Barco replacement parts as they may degrade the
safety of this projector.
•Projection rooms must be well ventilated or cooled in order to avoid heat buildup.
•Let the projector cool down completely before storing. Remove cord from the projector when storing.
3.4 To prevent projector damage
Preventing Projector Damage.
