Usage Guidelines

Cautions Concerning the Laser Pointer
The laser pointer on the remote control emits a laser
beam from the laser light window. This is a Class II
laser which may impair your sight if directed into the
eyes. The three marks shown on the right are caution
labels for the laser beam.
• Do not look into the laser light 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
41°F and 104°F ( 5°C and
• Use of controls or adjustments, or performance of proce-
dures other than those specified herein may result in haz-
ardous 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. 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 Authorized Sharp Industrial LCD Products Dealer or
Service Center.
• Do not expose the projector to extreme heat or cold.
Operating temperature: 41°F to 104°F ( 5°C to
Storage temperature: 4°F to 140°F ( 20°C to
• Do not tilt the projector at an angle greater than 5°.
Notes on Operation
• 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 4 inches (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 in-
dicate 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." will flash in the upper-
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 29, when "TEMP." appears on the screen.
• 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.
Lamp Monitor Function
When the projector is turned on after the lamp has been used for 1,900 hours, the LAMP REPLACEMENT
indicator will light red and "LAMP" will flash in yellow on the screen to advise you to replace the lamp. See
pages 30 and 31 for replacing the lamp. If the lamp has been used for 2,000 hours, the projector power
will automatically turn off and the projector will enter standby mode. Refer to "Lamp/Maintenance Indica-
tors" on page 29, when "LAMP" appears on the screen.
Remote Control Handling Precaution
• Do not expose the remote control to shocks, liquids or high humidity. The remote control may not operate normally if
exposed to direct sunlight or other intense light sources. Should this occur, reposition the light source or the projector.
• When not using the remote control, turn off the Main Power switch to avoid draining the batteries.
