Operating method and cautions:
Tool: dust-free gloves or dust-free fingertips, dust-free cotton swab, isopropyl alcohol
and canned dry pure compressed air.
Spray the isopropyl alcohol onto the dust-free cotton swab, make the lens face your
eyes, gently pinch the side edge of the lens with the thumb and forefinger of your left
hand, wipe the front and back of the lens in one direction from left to right or from top
to bottom with dust-free cotton swab held in the right hand ( remember not to wipe
the lens back and forth to avoid the second contamination), and blow the surface of
the lens with dry pure compressed air to ensure there is no dust on the lens.
