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 microfiber 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 microfiber 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.
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, microfiber 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, microfiber 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.
