Data Projector Operation Manual

8
Observe the following safeguards when setting up your
projector.
Caution concerning the lamp unit
Potential hazard of glass particles if lamp
ruptures. In case of lamp rupture, contact
your nearest Sharp Authorized Projector
Dealer or Service Center
for replacement.
See “Regarding the Lamp”
on page
60.
Caution 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 vents and lens must be
cleaned more often. 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
Authorized Projector Dealer or Service
Center.
Rest your eyes occasionally.
Continuously watching the screen for long
hours will cause eye strain. Take regular
breaks to rest your eyes.
Do not set up the projector in places
exposed to direct sunlight or bright light.
Position the screen so that it is not in direct
sunlight or room light. Light falling directly
on the screen washes out the colors,
making viewing diffi cult. Close the curtains
and dim the lights when setting up the
screen in a sunny or bright room.
Caution regarding placing of the projector
Place the projector on a level site within the
adjustment range (9 degrees) of the
adjustment foot.
After the projector is purchased, a faint
smell from the vent may appear when the
power is fi rst turned on. This is normal and
is not a malfunction. It will disappear after
the projector is used for a while.

When using the projector in high-
altitude areas such as mountains (at
altitudes of approximately 1,500
meters (4,900 feet) or more)
When you use the projector in high-altitude
areas with thin air, set “Fan Mode” to
“High”. Neglecting this can affect the
longevity of the optical system.
Use the projector at altitudes of 2,300
meters (7,500 feet) or less.
Warning about placing the projector in
a high position
When placing the projector in a high
position, make certain it is carefully secure
to avoid personal injury caused by the
projector falling down.
Do not subject the projector to hard
impact and/or vibration.
Protect the lens so as not to hit or damage
the surface of the lens.
Avoid locations with extremes of
temperature.
The operating temperature of the projector
is from 41°F to 95°F (+5°C to +35°C).
The storage temperature of the projector is
from –4°F to 140°F (–20°C to +60°C).
Do not block the exhaust and intake
vents.
Allow at least 11
13
/
16
inches (30 cm) of
space between the exhaust vent and the
nearest wall or obstruction.
Ensure that the intake vent and the exhaust
vent are not obstructed.
If the cooling fan becomes obstructed, a
protection circuit will automatically put the
projector into Standby mode to prevent
overheat damage. This does not indicate a
malfunction. (See pages 58 and 59.)
Remove the projector power cord from the
wall outlet and wait at least 10 minutes.
Place the projector where the intake and
exhaust vents are not blocked, plug the
power cord back in and turn on the
projector. This will return the projector to
the normal operating condition.
