SAFETY CHECK-OUT  
TABLE OF CONTENTS  
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.  
4.TEST MODE ..................................................................... 13  
2. A battery-operated AC milliammeter. The Data Precision 245  
digital multimeter is suitable for this job.  
5. ELECTRICAL ADJUSTMENTS ............................... 16  
3. Measuring the voltage drop across a resistor by means of a  
VOM or battery-operatedAC 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

TEST MODE  
4-1. PRECAUTIONS FOR USE OF TEST MODE  
1
As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is  
stopped before setting and removing it.  
Even if the §EJECT button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not  
stop rotating.  
Therefore, it will be ejected while rotating.  
Be sure to press the §EJECT button after pressing the EDIT/NO button and the rotation of disc is stopped.  
The erasing-protection tab is not detected in the test mode. Therefore, operating in the recording laser emission mode and pressing the  
rREC button, the recorded contents will be erased regardless of the position of the tab. When using a disc that is not to be erased in the  
test mode, be careful not to enter the continuous recording mode and traverse adjustment mode.

1) When replacing the following parts, perform the adjustments  
and checks with ¬ in the order shown in the following table.  
2) Set the test mode when performing adjustments.  
After completing the adjustments, exit the test mode.  
3) Perform the adjustments in the order shown.  
4) Use the following tools and measuring devices.  
• Check Disc (MD) TDYS-1  
laser tap  
Optical pick-up flexible board  
(Parts No. 4-963-646-01)  
• Laser power meter LPM-8001 (Parts No. J-2501-046-A)  
• Oscilloscope (Measure after performing CAL of prove.)  
• Digital voltmeter  
• Thermometer  
• Jig for checking BD board waveform  
(Parts No. : J-2501-124-A)  
5) When observing several signals on the oscilloscope, etc.,  
make sure that VC and ground do not connect inside the  
oscilloscope.  
(VC and ground will become short-circuited.)  
6) Using the above jig enables the waveform to be checked without  
the need to solder.  
(Refer to Servicing Note on page 4.)  
Note :When performing laser power checks and adjustment  
(electrical adjustment), use of the new MD laser power meter  
8010S (J-2501-145-A) instead of the conventional laser power
