SERVICE NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNITThe laser diode in the optical pick-up block may suffer electrostaticbreakdown because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic breakdown and also usethe procedure in the printed matter which is included in the repairparts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission, ob-serve from more than 30 cm away from the objective lens.

Notes on Chip Component Replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

CAUTIONUse of controls or adjustments or performance of procedures otherthan those specified herein may result in hazardous radiationexposure.

This compact disc player is classified as a CLASS 1 LASERproduct. The CLASS 1 LASER PRODUCT label is located on theexterior.

THIS NOTE IS COMMON FOR PRINTED WIRINGBOARDS AND SCHEMATIC DIAGRAMS.(In addition to this, the necessary note isprinted in each block.)

for schematic diagram:• All capacitors are in µF unless otherwise noted. pF: µµF

50 WV or less are not indicated except for electrolyticsand tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise

specified.• % : indicates tolerance.• f : internal component.• C : panel designation.

• A : B+ Line.• Power voltage is dc 14.4V and fed with regulated dc power

supply from ACC and BATT cords.• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal produc-tion tolerances.

• Waveforms are taken with a oscilloscope.Voltage variations may be noted due to normal produc-tion tolerances.

• Circled numbers refer to waveforms.• Signal path.

F : FMf : MW/LWJ : CD

for printed wiring boards:• X : parts extracted from the component side.• Y : parts extracted from the conductor side.• x : parts mounted on the conductor side.• a : Through hole.• : Pattern from the side which enables seeing.

(The other layer’s patterns are not indicated.)

Caution:Pattern face side: Parts on the pattern face side seen from the(Side B) pattern face are indicated.Parts face side: Parts on the parts face side seen from the(Side A) parts face are indicated.

Note: The components identified by mark 0 or dotted linewith mark 0 are critical for safety.Replace only with part number specified.
