How to clean
Projection Lens
As required
CLEAN:
A small amount of dust on the
lens has very little effect on picture quality.
Clean only if absolutely necessary.
To clean:
Moisten a
clean (not-reused),
lint-free cloth with a high-quality optical
cleaning fluid. Wipe the cloth in a single
continuous motion across the lens surface.
Discard the cloth after cleaning. Use
compressed air to remove any particles
remaining on the lens.
NEVER
use a cleaning solvent that
contains ammonia. Avoid lens contact with
Xylene and Ether.
As required
CLEAN
(glass only):
It is important to never
touch the glass surface of the lamp. Any oil
left by fingerprints will seriously degrade a
lamp’s performance or cause “hotspots”,
which can lead to an accumulation of
intense heat in the touched area and cause
the lamp to shatter.
Clean
the glass exit
surface of the lamp module only when
absolutely necessary.
NOTE:
Not applicable to the 275W lamp
used in the RPMSP-D275U model since it
does not have a glass front.
To clean
:
Wait
until the lamp is completely
cool. Moisten a clean, lint-free cotton cloth
with isopropyl alcohol and gently wipe the
surface of the glass in a circular motion
until clean.
