CAPACITOR ELECTRICAL DISCHARGE PROCESSING
When checking the board, for the electric shock prevention, con-
nect the resistors to respective parts to discharge.
Discharge at capacitor (Ref. No C27)
Discharge method 1
Connect the resistors to both ends of capacitor (Ref. No. C27) on
the switching regulator (SSN-161AD) to discharge.

(for C27)
Discharge method 2
When connecting the resistor to both ends of capacitor (Ref.
No. C27) on the switching regulator (SSN-161AD) is dif
fi
cult,
discharge by connecting the resistor between fuse (Ref. No. F4)
and jumper (Ref. No. J26, J24, J94).
Note:
Be careful not to short-circuit, because between the terminal is close.

Discharge at capacitor (Ref. No C18 and C20)
Discharge by connecting the resistor between pin 1, 2 (+VH) and
pin 8, 9 (–VH) of connector (Ref. No, CN2) on the switching
regulator board.
