Cautions Concerning the Setup of the Projector
40˚C
5˚C
• The exhaust vent, the lamp cage cover and adjacent areas may be extremely
hot during projector operation. To prevent injury, do not touch these areas until
they have sufficiently cooled.
• Allow at least 10 cm of space between the cooling fan (exhaust vent) and the
nearest wall or obstruction.
• If the cooling fan becomes obstructed, a protection device will automatically
turn off the projector lamp. This does not indicate a malfunction. Remove the
projector power cord from the wall outlet and wait at least 10 minutes. Then
turn on the power by plugging the power cord back in. This will return the
projector to the normal operating condition.
Notes on Operation
Temperature Monitor Function
If the projector starts to overheat due to setup problems or a dirty air filter, “TEMP.”
and “ ” will flash in the lower-left corner of the picture. If the temperature continues
to rise, the lamp will turn off, the TEMPERATURE WARNING indicator on the
projector will flash, and after a 90-second cooling-off period the power will shut
off. Refer to “Lamp/Maintenance Indicators” on page 38, for details.
• The cooling fan regulates the internal temperature, and its performance is
automatically controlled. The sound of the fan may change during projector operation
due to changes in the fan speed.
The laser pointer on the “Power” remote control emits a laser beam from the
laser pointer window. This is a Class
II
laser which may impair your sight if
directed into the eyes. The two marks shown on the left are caution labels for
the laser beam.
• Do not look into the laser pointer window or shine the laser beam on yourself or
others. (The laser beam used in this product is harmless when directed onto
the skin. However, be careful not to project the beam directly into the eyes.)
• Always use the laser pointer at temperatures between
5°C and
40°C.
• Use of controls or adjustments, or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Cautions Concerning the Laser Pointer
Lamp Monitor Function
When the projector is turned on after the lamp has been used for 1,400 hours,
“LAMP” and “ ” will flash in the lower-left corner of the picture to advise you to
replace the lamp. If the lamp has been used for 1,500 hours, the projector power
will automatically turn off and the projector will enter standby mode. Refer to
“Lamp/Maintenance Indicators” on page 38, for details.

CAUTION
• This product contains a low power laser device. To ensure continued safety, do not
remove any cover or attempt to gain access to the inside of the product. Refer all
serving to qualified personnel.
For minimal servicing and to maintain high image quality, SHARP recommends
that this projector be installed in an area free from humidity, dust and cigarette
smoke. When the projector is subjected to these environments, the lens and
filter must be cleaned more often. Periodically the filter should be replaced
and the projector should be cleaned internally. As long as the projector is
properly maintained in this manner, use in these environments will not reduce
the overall operation life. Please note that all internal cleaning must be
performed by an Authorised Sharp Industrial LCD Products Dealer or Service
Centre.
