SAFETY CHECK-OUT
(US model only) After correcting the original service problem, perform the following safety checks 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
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 microampers). 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. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 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 2V AC range are suitable. (See Fig. A)

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT 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 pickup block. Therefore, when checking the laser diode emission, observe 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 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. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Note on Schematic Diagram: · All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. · All resistors are in and 1/4 W or less unless otherwise specified. ¢ · : internal component. · C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. · · · · · Note: Les composants identifiés par une marque ! sont critiques pour la sécurité. Ne les remplacer que par une piéce portant le numéro spécifié. Note on Printed Wiring Boards: · X : parts extracted from the component side. p : parts mounted on the conductor side. · ® · : Through hole. · b : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.) Caution: Pattern face side: (Side B) Parts face side: (Side A) Parts on the pattern face side seen from the pattern face are indicated.

SECTION 8 EXPLODED VIEWS
NOTE: · -XX, -X mean standardized parts, so they may have some differences from the original one. · Items marked "*" are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. · · The mechanical parts with no reference number in the exploded views are not supplied. Hardware (# mark) list and accessories and packing materials are given in the last of this parts list.
The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. Les composants identifiés par une marque ! sont critiques pour la sécurité. Ne les remplacer que par une pièce portant le numéro spécifié.
