4. DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR

JAPANESE

The power supply capacitor (ST-114 board C8404, 8405) of the flash are charged up to the maximum 300V potential. There is a danger of electric shock by this high voltage when the capacitors are 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 1k�/1W (1-215-869-11) Wrap insulating tape fully around the reads of the resistor to prevent electric shock.
