be blocked or covered. The projector should never be placed near or over a
radiator or heat register. The projector should not be placed in an enclosure
unless proper ventilation is provided.
Do not push objects of any kind into the projector through the ventilation
openings. They may touch dangerous voltages or short-out components resulting
in a fire or shock hazard. Do not spill liquids of any kind into the projector.
Should an accidental spill occur, immediately unplug the projector and have it
serviced by a qualified service technician.
If any of the following conditions exist, unplug the projector and refer service to
qualified service personnel.
•
The power cord has been damaged.
•
The internal cooling fans do not come on when the projector is first turned on.
•
Liquid has been spilled into the projector.
•
The projector has been exposed to excessive moisture.
•
The projector does not operate normally.
•
The projector has been dropped or the case has been damaged.
•
Projector performance has deteriorated.
Do not attempt to service the projector yourself. All servicing must be performed
by a qualified Electrohome service technician. If replacement parts are required,
it is important that only Electrohome-approved parts are used. Other parts may
result in fire, electric shock or risk of personal injury.
Clean the projector when required. Always unplug the projector before cleaning.
To avoid the risk of scratching the lens, clean the lens only if absolutely
required—keep in mind that a small amount of dust on the lens will have very
little effect on picture quality. If you must clean the lens, use a DRY soft cotton
cloth. Dust gently in a circular motion.
It is important to never touch the sapphire (glass) surface of the lamp, as the oil
imprint will seriously degrade lamp performance. Should you accidentally touch
the surface of the lamp, clean gently with a lint-free cloth moistened with
isopropyl alcohol.
Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do
not use liquid or aerosol cleaners.
The standard IR Remote Keypad uses four AA size, 1.5V alkaline batteries. To
install new batteries, open the battery compartment at the back side of the
keypad by pulling on the raised portion of the cover as shown (Figure 4-1).
