Clean the lens only when absolutely necessary.
a small amount of dust on the lens has very little
effect on picture quality.
To clean: Use a soft lint-free cloth without any
chemicals. Use only a high-quality coated optics
cleaning fluid, which can be purchased from
most camera supply stores. apply the coated
optics fluid directly onto the lint-free cloth until
moistened. Wipe in a single sweep across the
surface of the lens. To avoid scratching the lens
do not scrub or rub in a circular motion. Discard
the cloth after every use. Do not use cleaning
tools treated with ether. Do not use cleaning
solvents that contain ammonia. Use compressed
air to remove any particles remaining on the
lens.
Clean: Clean if absolutely necessary. never
touch the glass surface of the lamp. Fingerprints
left on the glass will seriously degrade lamp
performance or cause "hotspots" which can
lead to an accumulation of intense heat in the
touched area and cause the lamp to shatter.
To clean: Wait until lamp is cool. moisten
a clean, lint-free cotton cloth with isopropyl
alcohol and gently rub the surface of the glass
in a circular motion until clean.
RePlaCe: refer to 4.4 Lamp and Filter
Replacement procedure later in this section.
Clean: Clean dust from external covers using
a clean, lint free cotton cloth as required.
nOTe: Before cleaning the modules, it is
recommended that you install the lens cap. This
will keep dust particles from settling on the glass
surface of the lens.
