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. ln case problems remain, the customer
is
requested to contact
the
workshop directly.
The lens
cleaning (method @) 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
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. lt
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
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.
