SAFETY CHECK-OUT  
TABLE OF CONTENTS  
After correcting the original service problem, perform the follow-  
ing 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). Leak-  
age 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.

5. ELECTRICAL ADJUSTMENTS ............................... 22  
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 aVOM  
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 pas-  
sive VOM that is suitable. Nearly all battery operated digital  
multimeters that have a 2V AC range are suitable. (See Fig. A)

• Digital voltmeter  
• Thermometer  
• Jig for checking BD board waveform  
(Parts No. : J-2501-149-A)  
view directly from the top as this may lose your eye-sight.  
5-3. PRECAUTIONS FOR USE OF OPTICAL PICK-  
UP (KMS-260A)  
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 connect-  
ing 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.  
5) When observing several signals on the oscilloscope, etc.,  
make sure thatVC and ground do not connect inside the oscillo-  
scope.  
(VC and ground will become short-circuited.)  
6) Using the above jig enables the waveform to be checked without  
the need to solder.  
pick-up  
flexible board  
(Refer to Servicing Note on page 6.)  
7) As the disc used will affect the adjustment results, make sure  
that no dusts nor fingerprints are attached to it.  
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 meter is convenient.  
It sharply reduces the time and trouble to set the laser power meter  
sensor onto the objective lens of the optical pick-up.
