e.g. 7122 707 48001
e.g. PM2534
Ri=50:
e.g. PM5326
S/N and distortion meter e.g. Sound Technology ST1700B
Use a bandpass filter to eliminate hum (50Hz, 100Hz) and disturbance from the pilottone (19kHz, 38kHz).

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.
GB Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used Safety components are marked by the symbol

4 LIQUID LENS CLEANING
For sets which are compatible with CD-RW discs use CD-RW Printed Audio Disc ....................7104 099 96611 TR 3 (Fingerprint) TR 8 (600µ Black dot) maximum at 01:00 • playback of these two tracks without audible disturbance playing time for: Fingerprint 10seconds Black dot from 00:50 to 01:10 • jump forward/backward (search) within a reasonable time
For all other sets use CD-DA SBC 444A..................................4822 397 30245 TR 14 (600µ Black dot) maximum at 01:15 TR 19 (Fingerprint) TR 10 (1000µ wedge)
• playback of all these tracks without audible disturbance playing time for: 1000µ wedge 10seconds Fingerprint 10seconds Black dot from 01:05 to 01:25 • jump forward/backward (search) within a reasonable time
2 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.
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. 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.
