@
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 an'
may
not be damaged
in order to
guarantee
its
full functio.-_
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.
