MEASUREMENTS AND SETTINGS MECHANICAL MEASUREMENTS AND SETTINGS Height adjustment of the turntable (see Fig.) This setting requires the device to be in normal operating mode. Service supports 4822 395 30202 can be used for this Play from CD 4822 397 30086 track 1 or (CD without defects). Connect a DC voltmeter across resistor 3240 on the SERVO PCB.

Adjusting the angle setting When adjusting the angle of the plate-light path in the factory, a compromise was sought between minimal angular deviation and minimal friction of the arm. If the measurement shows that the angle falls outside the given tolerance, the angle must NOT be adjusted to a minimum deviation, but just within the tolerance.

ELECTRICAL MEASUREMENTS AND ADJUSTMENTS Adjusting the offset control Specification Measurement (see SERVO PCB) Put the servo-µp into service mode by simultaneously pressing the power switch and the stop keys. Connect a DC voltmeter between point 14 of IC6215 and ground. With resistor 3315 regulate the voltage to 0V.

Adjusting the focus bandwidth Laser power supply (NEG.VOLT.PH.) Since the light pen is very sensitive to static charges, when measuring and adjusting the laser power, the tools and yourself must have the same potential as the CD mechanism. Make a measurement setup according to the figure. Play from test CD 4822 397 30096 track 1 (CD without defects).
