To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday´s cage.
Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz).

SERVICE AIDS
GB WARNING
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.

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.

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
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.
