It is advised to us

22、e “Cleaning Solvent The actuator is a very precise mechanical component and may not be damaged in order to 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 a
