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.  
6. DIAGRAMS  
2. A battery-operated AC milliammeter. The Data Precision 245  
digital multimeter is suitable for this job.

voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-  
amples of a passive VOM that is suitable. Nearly all battery  
operated digital multimeters that have a 2 V AC range are suit-  
able. (See Fig. A)

• 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 [MENU/NO] button and the rotation of disc is stopped.

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 con-  
necting 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 that VC and ground do not connect inside the oscil-  
loscope.  
(VC and ground will become short-circuited)  
6. Using the above jig enables the waveform to be checked with-  
out the need to solder.

7. As the disc used will affect the adjustment results, make sure  
that no dusts nor fingerprints are attached to it.  
Laser power meter  
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 conve-  
nient.
