Discharging of the Flashlight Power Supply

The capacitor which is used as power supply of flashlight is charged
with 200 V to 300 V voltage. Discharge this voltage before start-
ing disassembly in order to protect service engineers from electric
shock during disassembly.
Discharge procedure
1. Remove the FR-181 board, and disconnect the harness from
CN404 on the BT-006 board.
2. Fabricate the short jig as shown in Fig. 5-1-5 locally by your-
self. Connect the short jig to the pin 1 and pin 2 of CN404
on the BT-006 board. Allow ten seconds to discharge the volt-
age.
