blocked by placing the projector on a bed, sofa, rug,
or other similar surface. This projector should 
never be placed near or over a radiator or heat 
register.

installation such as a book case unless proper 
ventilation is provided.

Never push objects of any kind into this projector 
through cabinet slots as they may touch dangerous

a fire or electric shock. Never spill liquid of any kind 
on the projector.

Do not install the projector near the ventilation duct 
of air-conditioning equipment.

This projector should be operated only from the type

anything to rest on the power cord. Do not locate this 
projector where the cord may be damaged by persons 
walking on it.

Do not attempt to service this projector yourself

or frayed.

b. If liquid has been spilled into the projector.
c. If the projector has been exposed to rain or water.
d. If the projector does not operate normally by 

following the operating instructions. Adjust only 
those controls that are covered by the operating 
instructions as improper adjustment of other 
controls may result in damage and will often 
require extensive work by a qualified technician t 
restore the projector to normal operation.

e. If the projector has been dropped or the 

cabinet has been damaged.

f. When the projector exhibits a distinct change in 

performance-this indicates a need for service.

When replacement parts are required, be sure the 
service technician has used replacement parts 
specified by the manufacturer that have the same 
characteristics as the original part. Unauthorized 
substitutions may result in fire, electric shock, or 
injury to persons.

Upon completion of any service or repairs to this 
projector, ask the service technician to perform routine 
safety checks to determine that the projector is in 
safe operating condition.
