    Important safety instructions
    Your projector is designed and tested to meet the latest standards for safety of information 
    technology equipment. However, to ensure safe use of this product, it is important that you 
    follow the instructions mentioned in this manual and marked on the product. 
    Safety Instructions
    1.Please read this manual before you 
    operate your projector. Save it for 
    future reference. 
    2.Do not look straight at the projector 
    lens during operation. The intense 
    light beam may damage your eyes. 
    3.Refer servicing to qualified service 
    personnel. 4.Always open the lens shutter or 
    remove the lens cap when the 
    projector lamp is on. 
    5. In some countries, the line voltage is 
    NOT stable. This projector is designed 
    to operate safely within a mains 
    voltage between 100 to 240 volts AC, 
    but could fail if power cuts or surges 
    of ±10 volts occur. In areas where the 
    mains voltage may fluctuate or cut 
    out, it is recommended that you 
    connect your projector through a 
    power stabilizer, surge protector or 
    uninterruptible power supply (UPS). 
    6. Do not block the projection lens with 
    any objects when the projector is 
    under operation as this could cause 
    the objects to become heated and 
    deformed or even cause a fire. To 
    temporarily turn off the lamp, press 
    BLANK on the projector or remote 
    control. 
    						
    							Important safety instructions 4  
    Safety Instructions (Continued)
    7. The lamp becomes extremely hot 
    during operation. Allow the 
    projector to cool for approximately 
    45 minutes prior to removing the 
    lamp assembly for replacement. 
    8. Do not operate lamps beyond the 
    rated lamp life. Excessive operation 
    of lamps beyond the rated life could 
    cause them to break on rare 
    occasions. 
    9. Never replace the lamp assembly or 
    any electronic components unless 
    the projector is unplugged. 10. Do not place this product on an 
    unstable cart, stand, or table. The 
    product may fall, sustaining serious 
    damage. 
    11. Do not attempt to disassemble this 
    projector. There are dangerous high 
    voltages inside which may cause 
    death if you should come into 
    contact with live parts. The only 
    user serviceable part is the lamp 
    which has its own removable cover.
    Under no circumstances should you 
    ever undo or remove any other 
    covers. Refer servicing only to 
    suitably qualified professional 
    service personnel.
    12. When the projector is under 
    operation, you may sense some 
    heated air and odor from its 
    ventilation grill. It is a normal 
    phenomenon and not a product 
    defect. 
    						
    							Important safety instructions 5        
    Safety Instructions (Continued)
    13. Do not place this projector in any of the 
    following environments. 
    - Space that is poorly ventilated or confined. 
    Allow at least 50 cm clearance from walls 
    and free flow of air around the projector. 
    - Locations where temperatures may 
    become excessively high, such as the 
    inside of a car with all windows rolled up.
    - Locations where excessive humidity, dust, 
    or cigarette smoke may contaminate 
    optical components, shortening the 
    projectors life span and darkening the 
    image.
    - Locations near fire alarms
    - Locations with an ambient temperature 
    above 40°C / 104°F
    - Locations where the altitudes are higher 
    than 3000 m (10000 feet).
    14. Do not block the ventilation holes. 
    - Do not place this projector on a blanket, 
    bedding or any other soft surface. 
    - Do not cover this projector with a cloth or 
    any other item. 
    - Do not place inflammables near the 
    projector.   
    If the ventilation holes are seriously 
    obstructed, overheating inside the 
    projector may result in a fire.
    15. Always place the projector on a level, 
    horizontal surface during operation.
    - Do not use if tilted at an angle of more 
    than 10 degrees left to right, nor at angle 
    of more than 15 degrees front to back. 
    Using the projector when it is not fully 
    horizontal may cause a malfunction of, or 
    damage to, the lamp. 
    16. Do not stand the projector on end 
    vertically. Doing so may cause the 
    projector to fall over, causing injury or 
    resulting in damage to the projector.

    Safety Instructions (Continued)
    17. Do not step on the projector or place 
    any objects upon it. Besides probable 
    physical damage to the projector, doing 
    so may result in accidents and possible 
    injury.
    18. Do not place liquids near or on the 
    projector. Liquids spilled into the 
    projector may cause it to fail. If the 
    projector does become wet, disconnect 
    it from the power supplys wall socket 
    and call BenQ to have the projector 
    serviced.
    19. This product is capable of displaying 
    inverted images for ceiling mount 
    installation. 
    Use only BenQs Ceiling Mount Kit for 
    mounting the projector and ensure it is 
    securely installed. 
    Ceiling mounting the projector
    We want you to have a pleasant 
    experience using your BenQ projector, 
    so we need to bring this safety matter to 
    your attention to prevent possible 
    damage to person and property.
    If you intend to mount your projector 
    on the ceiling, we strongly recommend 
    that you use a proper fitting BenQ 
    projector ceiling mount kit and that 
    you ensure it is securely and safely 
    installed.
    If you use a non-BenQ brand projector 
    ceiling mount kit, there is a safety risk 
    that the projector may fall from the 
    ceiling due to an improper attachment 
    through the use of the wrong gauge or 
    length screws.
    You can purchase a BenQ projector 
    ceiling mount kit from the place you 
    purchased your BenQ projector. BenQ 
    recommends that you also purchase a 
    separate Kensington lock compatible 
    security cable and attach it securely to 
    both the Kensington lock slot on the 
    projector and the base of the ceiling 
    mount bracket. This will perform the 
    secondary role of restraining the 
    projector should its attachment to the 
    mounting bracket become loose.
