Maintenance
Before maintaining the projector
 fMake sure to turn of f the power before maintaining the projector. (x pages 35, 38)
 fWhen switching of

f the projector, make sure to follow the procedures in “Switching off the projector” (x   page   38).
Maintenance
Outer case
Wipe off dirt and dust with a soft, dry cloth.
 fIf the dirt is persistent, soak the cloth with water and wring it thorou\
ghly before wiping. Dry of

f the projector with a dry cloth.
 fDo not use benzene, thinner

, or rubbing alcohol, other solvents, or household cleaners. Doing so ma\
y deteriorate the outer case.
 fWhen using chemically treated dust cloths, follow the instructions writt\
en on its packaging.
Lens front surface
Wipe off dirt and dust from the front surface of the lens with a soft clean clo\
th.
 fDo not use a cloth that is fluf

fy, dusty, or soaked with oil/water.
 fSince the lens is fragile, do not use excessive force when wiping the le\
ns.
Attention
 fThe lens is made of glass. Impacts or excessive force when wiping may sc\
ratch its surface. Please handle with care.
Cleaning inside the projector
Depending on the environment or use conditions such as use in a dusty pl\
ace, dust accumulated around the intake and exhaust ports will 
degrade the circulation of ventilation, cooling and exhaust heat, and br\
ightness may decrease as a result.
If the brightness reduces noticeably or the light source goes off, clean inside the projector or ask your dealer about replacement of th\
e light 
source unit.
