Notes

Do not clean the exterior surface of the output widow mirror with tools such as tampon; otherwise the output power will be seriously affected. The followings are the designated methods to clean up pollution in the exterior surface of window mirror.

1) When the mirror is polluted, do not turn on the laser.
2) Blow the mirror surface sideways with an air blower.
3) Spray the pure alcohol on the mirror surface with sprayer.
4) Turn on the laser after the alcohol gets fully volatilized.
