SECTION 1 SERVICING NOTES
SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check 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 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 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. 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 lowvoltage 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. (See Fig. A)

SECTION 5 ELECTRICAL ADJUSTMENTS
Precautions for Checking Laser Diode Emission
To check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight.
Precautions for Adjustments
1) When replacing the following parts, perform the adjustments and checks with ® in the order shown in the following table.
Optical Pick-up IC171 1. Temperature compensation offset adjustment 2. Laser power adjustment 3. Traverse adjustment 4. Focus bias adjustment 5. Error rate check G ¬ ¬ ¬ ¬ ¬ BD Board D101 ¬ IC101, IC121, IC191 ¬
Precautions for Use of optical pick-up (KMS-210A)
As the laser diode in the optical pick-up is easily damaged by static electricity, solder the laser tap of the flexible board when using it.Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder. Also take adequate measures to prevent damage by static electricity. Handle the flexible board with care as it breaks easily.
