Cleaning the Projector

Cleaning the Projection Lens

Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that
contains a small amount of non-abrasive camera lens
cleaner, or use a lens cleaning paper or commercially avail-
able air blower to clean the lens.
Avoid using an excessive amount of cleaner. Abrasive
cleaners, solvents, or other harsh chemicals might scratch
the surface of the lens.

Cleaning the Projector Cabinet

Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning cloth.
When the cabinet is heavily soiled, use a small amount of
mild detergent and finish with a soft dry cleaning cloth. Avoid
using an excessive amount of cleaner. Abrasive cleaners,
solvents, or other harsh chemicals might scratch the sur-
face of the cabinet.
When the projector is not in use, put the projector in an ap-
propriate carrying case to protect it from dust and scratch-
es.
CAUTION
Do not use any flammable solvents or air sprays on the pro-
jector and in its vicinity. The explosion or fire hazard may
occur even after the AC power cord is unplugged because
the temperature inside the projector is extremely high due to
the lamps. In addition, there is a risk that the internal parts
may be damaged not only by the flammable air spray but
also by the cold air.
