Part Description Frequency Action
Lens As required 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.
As required
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.

Covers (External)
As required 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.
