22、ID LENS CLEANING Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “Cleaning Solvent The actuator is a very precise mechanical component and may not be damaged in order to

23、guarantee its full function. Clean the lens gently (dont press too hard) with a soft and clean cotton bud moistened with the special lens cleaner. The direction of cleaning must be in the way as indicated in the picture below. Before touching the lens it is advised to clean the surface of the lens b
