NOTE:
•  -XX, -X mean standardized parts, so they may have some differences from the original 

one.

•  Items marked “*” are not stocked since they are seldom required for routine service. 

Some delay should be anticipated when ordering these items.

•  The mechanical parts with no reference number in the exploded views are not sup-

plied.

•  Due to standardization, replacements in the parts list may be different from the parts 

specified in the diagrams or the components used on the set.

The charging capacitor (C901) of the MA-461 Flexible flexible 
board is charged up to the maximum 315 V potential.
There is a danger of electric shock by this high voltage when the 
capacitor is handled by hand.  The electric shock is caused by the 
charged voltage which is kept without discharging when the main 
power of the unit is simply turned off.  Therefore, the remaining 
voltage must be discharged as described below.

To preparing the short jig, a small clip is attached to each end of 
a resistor of 1 k

Ω /1 W (1-215-869-11).

Wrap insulating tape fully around the leads of the resistor to 
prevent electrical shock.

•  Make sure that the flat cable and flexible board are not cracked 

of bent at the terminal.

  Do not insert the cable insufficiently nor crookedly.

•  When remove a connector, don’t pull at wire of connector. It is 

possible that a wire is snapped.

•  When installing a connector, don’t press down at wire of con-

nector. 

  It is possible that a wire is snapped.

•  Do not apply excessive load to the gilded flexible board.

Note: High-voltage cautions

Discharging the Capacitor
Short-circuit between two points 
with the short jig about 10 seconds.
