4. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR (DCR-PC105/PC105E)
The power supply capacitor (C6606) of the ST-084 board is charged up to the maximum 300V 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.
4-1. PREPARING THE SHORT JIG
To preparing the short jig. a small clip is attached to each end of a resistor of 1kΩ/1W (1-215-869-119)
Wrap insulating tape fully around the reads of the resistor to prevent electric shock.
4-2. DISCHARGING THE CAPACITOR (DCR-PC105/PC105E)
1 kΩ/1 W
Wrap insulating tape.

Discharging method (1):
1 Open the flash.
2 Remove the power supply (Battery or AC power adaptor).
3 Remove the ST cabinet (Upper).
4 Short-circuit between the Xenon tube anode and the GND
(GND of the accessory shoe) with the short jig about 10 seconds.
Discharging method (2):
1 Remove the power supply (Battery or AC power adaptor).
2 Refer to 2-2. to remove the cabinet (front) section.
3 Refer to 2-6. to release the cassette cover lock and remove the
cabinet (R) section.
4 Short-circuit between the TP6600 of the ST-084 board and the
GND (GND of the accessory shoe) with the short jig about 10
seconds.
