It is advised to use “Cleaning Solvent B4-No2”, available with codenumber 4822 389 10026. The actuator is a very precise mechanical component and may not be damaged in order to guarant

20、ee 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 by blowi

21、ng clean air over it. This to avoid that little particles make scratches on the lens.
