Cautions Concerning the Laser Pointer
The laser pointer on the 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
• Use of controls or adjustments, or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
Cautions Concerning the Setup of the Projector
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. If the projector is used in these environments, the lens and filter will
need to be cleaned (or the filter replaced) more often, and internal cleaning
may become necessary. As long as the projector is regularly cleaned, use in
these environments will not reduce the overall operation life of the unit. Internal
cleaning should only be performed by a Sharp Authorised LCD Projector
Dealer or Service Centre.
Notes on Operation
• The two marks shown on the left are caution labels for parts of the projector
that emit intense heat during operation.
• The exhaust vents, 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.
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 47, 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.
