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, immediately unplug the projector from the
power outlet 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 service technician only. If replacement parts are required, it is important
that only manufacturer-approved parts are used. Other parts may result in fire,
electric shock or risk of personal injury.
Clean the projector when required. Before cleaning, always unplug the projector from
the power outlet.
'
To avoid the risk of scratching the lens, clean the lens only if absolutely required. A
small amount of dust on the lens will have very little effect on picture quality. If the
lens must be cleaned, use a DRY soft cotton cloth. Clean gently in a circular motion.
'
It is important to never touch the glass surface of the lamp, as the oil imprint will
seriously degrade lamp performance. Should you accidentally touch the surface of
the lamp, clean carefully 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 IR remote keypad uses four AA size, 1.5V batteries (preferably alkaline). 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).
Remove the old batteries and properly discard. Wait a minute or two and place the
new batteries in the compartment, orienting the positive/negative of each battery
according to the labels in the compartment. When batteries are in place, replace the
cover by inserting its bottom edge first and snapping the top into place. Do not force.
NOTE: Always wait a minute or two when replacing batteries so that the internal
electronics discharge and can recognize the change.
