2. To prevent the decline,wipe process should be gentle
3.Wipe lens, do not wipe back and forth, do not brush with rough materials, because the
lens with a metal film, the film will lead to a damage of laser energy attenuation.
4.With absorbent cotton wipe can only can be used for one time. The cotton should be
