2. Demagnetize the playback head with a head demagnetizer.  
3. Do not use a magnetized screwdriver for the adjustments.  
4. After the adjustments, apply suitable locking compound to the  
parts adjusted.  
<Set the Test Mode>  
1. Set the “power select” switch (S501) is “A” position.  
2. Turn ON the regulated power supply. (All LEDs on the set  
lights up, and the clock is displayed.)  
5. The adjustments should be performed with the power supply  
voltage unless otherwise noted.  
Note: Press the [OFF] button, if the clock is not displayed.  
3. Push the preset [4] button.  
4. Push the preset [5] button.  
• Torque Measurement  
5. Press the preset [1] button for more than two seconds.  
6. Then the display indicates all lights, the test mode is set.

ELECTRICAL PARTS LIST  
KEY  
NOTE:  
When indicating parts by reference  
number, please include the board.  
• Due to standardization, replacements in the  
parts list may be different from the parts speci-  
fied in the diagrams or the components used  
on the set.  
Items marked “*” are not stocked since they  
are seldom required for routine service.  
Some delay should be anticipated when order-  
ing these items.  
• -XX and -X mean standardized parts, so they  
may have some difference from the original  
one.  
• RESISTORS  
All resistors are in ohms.  
METAL: Metal-film resistor.  
METAL OXIDE: Metal oxide-film resistor.  
F: nonflammable  
SEMICONDUCTORS  
In each case, u: µ, for example:  
uA. .  
: µA. .  
uPA. . : µPA. .  
uPC. . : µPC. .
