5-1-2 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.
<Notes>
O 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.
O 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.

Rush current may occur at the time for turning on the
power of the unit.
We recommend using an external DC power supply
capable to secure double or more capacity of the total
power consumption of the devices connected to the
unit such as the viewfinder and lights. Use a DC cable
with a capacity of 10A or more.
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.
