How to clean

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 lint-free 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 lint-free 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. Do not 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 (front glass only): 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. REPLACE: Refer to 4.4 Lamp Replacement

for instructions.

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.
