CUSTOMER INFORMATION

It is proposed to add an addendum sheet to the set which
informs the customer that the set has been checked
carefully - but no fault was found.
The problem was obviously caused by a scratched, dirty or
copy-protected CD. In case problems remain, 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.

FAST LENS CLEANING (dry brush)

Use lens cleaning CD

SBC AC300 ...........................................9082 100 00043

Insert the lens cleaning CD, press PLAY and follow the
voice guide´s instructions on the CD.

LIQUID 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 B4-No2”, available with codenumber
4822 389 10026.

The actuator is a very precise mechanical component and
may not be damaged in order to guarantee its full function.
Clean the lens gently (don’t 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 to avoid that little particles make scratches on
the lens.
