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 Service Center or Dealer for replacement.

 

See “Regarding the Lamp” on page 

48.

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 Service Center or Dealer. 

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 (±5 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 approximate-

ly 4,900 feet (1,500 meters) 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.

Warning about placing the projector in a high 

position

■  When placing the projector in a high position, ensure that 

it is secured carefully 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.

Rest your eyes occasionally.

■  Continuously watching the screen for long hours will 

cause eye strain. Be sure to occasionally rest your 
eyes.

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.

■  Be sure 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 indi-
cate a malfunction. (See page 

46.) Remove the projector 

power cord from the wall outlet and wait at least 10 min-
utes. 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.

■  When turning off the projector, the cooling fan runs to 

decrease the internal temperature for a while. Unplug 
the power cord after the cooling fan stops. The period 
the cooling fan runs will vary, depending on the circum-
stances and the internal temperature.

Caution regarding usage of the projector

■  When using the projector, be sure not to subject it to 

hard impact and/or vibration, as this can result in dam-
age. Take extra care with the lens. Before moving the 
projector, be sure to unplug the power cord from the wall 
outlet, and disconnect any other cables connected to 
it.

■  Do not carry the projector by holding the lens.

■  When storing the projector, re-attach the lens cap. (See 

page 

8.)

■  Do not expose the projector to direct sunlight or place 

next to heat sources. Doing so may affect the cabinet 
color or cause deformation of the plastic cover.

Other connected equipment

■  When connecting a computer or other audio-visual 

equipment to the projector, make the connections AFTER 
unplugging the power cord of the projector from the AC 
outlet and turning off the equipment.

■  Please read the operation manuals of the projector and 

the equipment to be connected for instructions on how 
to make the connections.

Using the projector in other countries

■  The power supply voltage and the shape of the plug may 

vary depending on the region or country you are using 
the projector in. When using the projector overseas, be 
sure to use an appropriate power cord for the country 
you are in.
