6、t Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may bedamaged by heat.Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 Cduring repairing. Do not touch the soldering iron on the same conductor of thecircuit board (w

7、ithin 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 radiationexposure.This appliance is classified as a CLASS 1 LASER product This label

8、 is located on the rear exteriorThe laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the

10、ical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNITLASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the

18、 before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws,and all other exposed metal parts for AC leakage.Check leakage as described below.LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to an

19、y exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microamperes.).Leakage current can be measured by any one of three methods.1.A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers instructions to use theseinstruments.2.A battery-opera

20、ted 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” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa

21、 SH-63Trd are examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2 V AC range are suitable.
