D-ILA Device Characteristics
Do not project still pictures or pictures that have still 
segments for a long period of time. The still parts of the 
picture may remain on the screen. This is a characteristic of 
D-ILA devices and not a malfunction. The picture will 
disappear over time.
When Unit is Unused for a Long Time
Prolonged disuse of the unit may effect an error on the 
functions. Turn on the power occasionally and operate the 
unit.
Viewing Advice
Looking at the screen continually for a prolonged time will 
cause your eyes to get tired. Allow your eyes to rest at 
intervals.
Usage Environment
zAvoid direct exposure of screen to direct sunlight and 
illumination. Block light using a curtain. Images can be 
well projected by darkening the brightness of the room.
zDo not use this unit in rooms with cigarette smoke or oily 
smoke. This may cause the unit to malfunction.
Parts Replacement
This unit contains parts (optical part, cooling fan, etc.) that 
require replacement to maintain its functioning. The 
estimated time for parts replacement varies greatly 
depending on the usage and environment. Please consult 
your authorized dealer for replacement. 
Maintenance Procedures
Dirt on the cabinet
zGently clean dirt on the cabinet with a soft cloth. In the 
case of heavy soiling, soak a cloth in water, wring dry and 
wipe, followed by wiping again with a dry cloth.
Pay attention to the following as the cabinet may 
deteriorate in condition or paint may come off.
•Do not wipe with thinner or benzene
•Do not spray volatile chemicals like insecticide
•Do not allow prolonged contact with rubber or plastic 
products
Dirt in the air inlets
zUse a vacuum cleaner to suck up the dirt. Otherwise, use 
a cloth to wipe off the dirt. If dirt is allowed to accumulate 
in the air inlets, the internal temperature cannot be 
adjusted and this may cause a malfunction.
Dirt on the lens
zClean the dirt using commercial blowers or lens cleaning 
papers for cleaning glasses and cameras.
Do not use fluid-type cleaning agents. This may lead to 
peeling of the surface coating film.
Transporting this Unit
When transporting this unit for repair or during house 
moving, attach the buffer material on the top and bottom of 
the lens for protection. Failure to do so may subject the lens 
to shock causing damage.
Attach the buffer material after adjusting the lens to the 
center position.
