Follow the manufacturers instructions to use theseinstruments.2.A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.3.Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indica-tion is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-amples of a passive VOM that is suitable. Nearly all batteryoperated digital multimeters that have a 2 V AC range are suit-able.

Therefore, when checking the laser diode emis-sion, observe from more than 30 cm away from the objective lens.NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNITMODEL IDENTIFICATION BACK PANEL ModelPart No.US model4-224-879-0sCanadian model4-224-879-1sAEP model4-224-879-2sAustralian model4-224-879-3sE model4-224-879-4sSingapore model4-224-879-5sSaudi Arabia model4-224-879-6sHOW TO OPEN THE DISC TABLE WHEN POWERSWITCH TURNS OFFInsert a tapering driver into the aperture of the unit bottom, andturn it in the direction of the arrow (to OUT direction).tabletapering driver*To close the disc table, turn the tapering driver in the reverse direction (to IN direction).Part No.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.Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur-ing repairing. Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times). Be careful not to apply force on the conductor when solderingor unsoldering.CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous ra-diation exposure.Carry out the “S curve check” in “CD section adjustment” andcheck that the S curve waveforms is output three times.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKThis appliance is classified as a CLASS 1 LASER product.The CLASS 1 LASER PRODUCT MARKING is located onthe rear exterior.4CD-TEXT TEST DISCThis unit is able to display the TEXT data (character information) written in the CD on its fluorescent indicator tube.The CD-TEXT TEST DISC (TGCS-313:4-989-366-01) is used for checking the display.To check, perform the following procedure.Checking Method:1. Set the test disc on a free tray, and chuck the disc.2. Press the B button and play back the disc.3. The following will be displayed on the fluorescent indicator tube.Display : 1kHz/0 dB/ L&R4.
