Table 4.1. Maintenance Guide

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	As required	Clean dust from external module covers
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.
