The problem was obviously caused by a scratched, dirty or copy-protected CD. In case problems remain,

20、 the customer is requested to contact the workshop directly. The lens cleaning (method 3) should be mentioned in the addendum sheet. The final wording in national language as well as the printing is under responsibility of the Regional Service Organizations. 4 LIQUID LENS CLEANING Because the materi

21、al 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 guarantee its full function. Clean

22、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 blowing clean air over it. This t
