servicing.
Action
CLEAN: Clean if absolutely necessary. A small
amount of dust on the lens has very little affect
on picture quality.
To clean: Apply a solvent such as acetone,
alcohol or vinegar sparingly to clean, lint-free
lens tissue. Wipe across the surface of the lens.
Do not scrub or rub tissue in circular motion, this
will scratch the lens. Do not reuse tissue. Do not
use cleaning tools treated with Ether. If particles
still appear on the lens, try using compressed air
to remove.
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 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.
