IMPORTANT SAFETY INSTRUCTIONS  
    
CAUTION
To prevent shock, do not open 
the cabinet. No user-serviceable 
parts inside. 
Please read this user’s guide 
before you operate your 
projector. Save this user’s guide 
for future reference.   
Do not look straight at the 
projector lens during 
operation. The intense light beam 
may damage your eyes. Refer servicing to qualified 
service personnel.    
Always open the lens shutter 
or remove the lens cap when 
the projector lamp is on.  
 In some countries, the line voltage 
is NOT stable. This projector is 
designed to operate safely within a 
bandwidth of 110 to 240 volts, but 
could fail if power cuts or surges of 
±10 volts occur. In these high-
risk areas, it is recommended 
to install a power stabilizer 
unit.

of lamps beyond the rated life could 
cause them to explode on rare 
occasions. 
3. Never replace lamp assembly or any 
electronic components unless the 
projector is unplugged. 4. Do not place this product on an 
unstable cart, stand, or table. The 
product may fall, sustaining serious 
damage. 
5. To reduce the risk of electric shock, 
do not disassemble this appliance.  
*Take it to a qualified technician when

inverted images for ceiling mount 
installation. Please use BenQ’s
