Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return 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 RCA WT-540A. Follow the manufacturers instructions to use these instruments. 2.A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3.Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable.

Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveforms is output three times. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical 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-UP BLOCK OR BASE UNIT HOW TO OPEN THE DISC TABLE WHEN POWER SWITCH TURNS OFF Insert a tapering driver into the aperture of the unit bottom, and turn it in the direction of the arrow (to OUT direction).

This set has the Aging mode for operation check of the mechanism deck. If a failure occurred The aging operation stops and a faulty status is displayed on the fluorescent indicator tube. If no failure occurs The aging operation continues repeatedly. NOTE: Do not use the test disc when performing aging. Aging will not be performed properly if discs with tracks shorter than 4 seconds are used. Procedure: 1. Press the POWER button and turn ON the power. 2. Set discs on all trays. (More than two discs if five are not available) 3. All mode: Press the CHECK, PLAY MODE and x buttons at the same time. Disc table mode: Press the CHECK, PLAY MODE and DISC SKIP buttons at the same time. Loading mode: Press the CHECK, PLAY MODE and EX-CHANGE buttons at the same time. 4.
