Part Description Frequency How to clean
Lens
As required 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 in single sweep 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.
Lamp (cleaning)
Clean as required Clean if absolutely necessary. Never touch
the glass surface of the lamp. Any oil (left by
fingerprints) 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.
Lamp (replacement)
As required Since the projector can be operated in several
lamp modes – lamp replacement intervals
may vary. If you notice a significant change
in the projector’s performance over a short
period of time check the lamp hours and
status of your lamps. See “Lamp
Replacement” later in this section for more
details and a complete procedure on lamp
replacement.
Adjuster
As required Remove dust and debris using a clean. lint-
free cloth.
Exterior Module
Covers
As required Clean dust from external module 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.
