DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR
The capacitor (ST-076 board C4208) of the flash unit is charged up to the maximum 300V potential. There is a danger of electric shock by this high voltage when the ST-076 board 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. 3-1. PREPARING THE SHORT JIG To preparing the short jig. a small clip is attached to each end of a resistor of 1k� /1W (1-215-869-11). Wrap insulating tape fully around the reads of the resistor to prevent electric shock.

COAXIAL CONNECTOR OF THE BLUETOOTH HARNESS (DCR-IP220/IP220E model)
When the coaxial connector of the Bluetooth harness 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 Bluetooth harness, and pull iPress the Stopper in the direction of the arrow using a rod/t out vertically toward the board.
