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 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. 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. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

30% amplitude modulation by 400Hz signal output level : as low as possible
set AM ANTENNA terminal (JK101)
Procedure: 1. Supply a 98 MHz signal at 28 dB from the ANTENNA terminal. 2. Tune the set to 98 MHz. 3. Adjust RV101 to the point (moment) when the TUNED indicator will change from going off to going on. Adjustment Location: MAIN board Null Adjustment

set Carrier frequency : 98 MHz Modulation : AUDIO 1 kHz, 75 kHz deviation (100%) Output level : 60 dB (at 75 open) FM ANTENNA terminal (JK101)
Procedure: 1. Set the frequency of the AM RF signal generator to 1000 kHz (at 10 kHz step) or 999 kHz (at 9 kHz step). 2. Tune the set to AM 1000 kHz (at 10 kHz step) or 999 kHz (at 9 kHz step). 3. Adjust IFT101 so that the reading on level meter becomes in maximum.
Procedure: 1. Supply a 98 MHz signal at 60 dB from the ANTENNA terminal. 2. Tune the set to 98 MHz. 3. Measure voltage between pin 21 and pin 23 of IC 101. Adjust T101 until the voltage becomes 0 V. Adjustment Location: MAIN board

Note :
1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10M impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. RF Level Check
oscilloscope CD board IC751 pin q; GND
Procedure : 1. Connect oscilloscope to pin q; (IC751). 2. Turned Power switch on. 3. Load a disc (YEDS-18) and playback. 4. Confirm that oscilloscope waveform is clear and check RF signal level is correct or not.
Note : Clear RF signal waveform means that the shape " " can be clearly distinguished at the center of the waveform.
