1-2. DISCHARGING OF THE FLASH UNIT’S CHARGING CAPACITOR
The charging capacitor of the FLASH unit is charged up to the maximum 300 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 DSC-F828 is simply turned off. Therefore, the remaining voltage
must be discharged as described below.
1-2-1. Preparing the Short Jig
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.
1-2-2. Discharging the Capacitor
Short circuits between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.
