Use of the external DC power supply

1 Connect the external DC power supply to the DC IN socket on the unit.

2 Turn on the power switch of the external DC power supply. (If the power switch is available on the external DC power supply.)

3 Turn on the POWER switch on the unit.

Inrush current is generated when the power of the unit is turned on. Insufficient power supply when turning on the power may cause a malfunction. We recommend using an external DC power supply with double the capacity of the total power consumption of the unit and any other connected device that is turned by interlocking with the power on of the unit (the viewfinder). Select the DC cord that is recommended for the external DC power supply.

Confirm the pin arrangements of the DC output connector of the external DC power supply and the DC IN socket on the unit, and connect the proper polarities to each other.

If the +12 V power supply is connected to the GND connector in error, it may cause a fire or failure of the unit.

Notes

If both the battery pack and the external DC power supply are connected, the electric power is supplied from the external DC power supply. While the external DC power supply is used, the battery can be mounted and removed on/from the unit.

When the external DC power supply is used, ensure that the power switch of the external DC power supply is turned on first and then the POWER switch on the unit is turned on. In the case of the reverse operation, a malfunction may occur on the unit since the output voltage of the external DC power supply is raised slowly.
