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).

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.
