Handle the power cord carefully and avoid excessive bending.
A damaged cord may cause electric shock or fire. For continued safe and reliable
operation, only use cables supplied by the manufacturer for power and signal connections.
Installation should be performed by an electrician with current knowledge of electrical
codes in the country of use.
Fluid Safeguards
Certain components of the projector contain fluid. If any fluid from the projector contacts
the skin, wash off with soap and water. If any fluid from the projector splashes into the
eyes, rinse with cool running water.
Ventilation and Foreign Object Retrieval
Ensure the 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 (see Section 4.3). Verify that vent ports are clear
of all obstructions.
Keep the projector free from foreign objects, such as hairpins, nails, paper, etc. Do not
attempt to retrieve such objects yourself or insert metal objects such as wire and
screwdrivers inside the unit. If an object falls inside the projector, unplug the projector
immediately and call a Hughes-JVC certified technician for removal.
