The capacitor (C4207) of the flash unit (FL-2960) is charged up to the maximum 300V potential. There is a danger of electric shock by this
high voltage when the flash unit (FL-2960) is 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.

To preparing the short jig. a small clip is attached to each end of a resistor of 1k

Ω/1W (1-215-869-11). Wrap insulating tape fully around the

reads of the resistor to prevent electric shock.

Remove the power supply (Battery or AC power adaptor).

2

Short-circuit between TP4201 of the flash unit (FL-2960) and the GND (Mechanism chassis) with the short jig about 10 seconds.

When the coaxial connector of the BT cable isn’t pulled out vertically toward the board, the connector may be damaged. So, when disconnecting
the connector, be sure to take the connector of the BT cable, and pull it out vertically toward the board.
