[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-P92 is simply turned off. Therefore, the remaining
voltage must be discharged as described below.
