Ventilation and Foreign Object Retrieval
CAUTION!
Ensure projector’s multiple fans are free from
obstructions and operating properly. Air filters are located at vent
ports on the cover. Air filters require periodic cleaning to ensure
adequate cooling of the projector (Section 4.3). Ensure that all
vent ports are clear of obstructions.
Keep the inside of the projector free from foreign objects, such as
hairpins, nails, paper, etc. Do not attempt to retrieve any object or
insert metal objects such as wire and screwdrivers inside the unit.
If an object falls inside the projector, immediately unplug the
projector and call a Hughes-JVC certified technician to remove
object.
