Discharging of the flashlight power supply

The capacitor which is used as power supply of flashlight is charged
with 200V to 300V voltage. Discharge this voltage before starting
adjustments in order to protect service engineers from electric shock
during adjustment.
Discharge procedure
1. Remove the power supply (AC power adaptor or battery).
2. Fabricate the discharging jig as shown in Fig. 5-1-4 locally by
yourself. Connect the discharging jig to the positive (+) and
negative (-) terminal of the flash voltage charge capacitor. Allow
ten seconds to discharge the voltage.
