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

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 the camera-recorder power switch ON.
Use of external DC power supply
Make sure that the output voltage of the external DC
power supply meets the rated voltage of the camera before
making a connection.
The output current of the external DC power supply should
be large enough to provide the connected camera with its
total amperage needs with a reasonable margin.
Use the following formula to calculate the total amperage
of the camera.
total power consumption ÷ voltage
When the power is turned on, a rush current occurs. If the
power supply is insufficient during this time, the camera
may be damaged. Therefore, we recommend using an
external DC power supply that provides at least twice
the total power consumed by the camera and all the
devices connected to the unit that power on when the
camera powers on (example: lens, wireless microphone
receiver). We also recommend using the proper DC cable
recommended for your external DC power supply.
When using an external power supply other than the
AC adapter, check the DC IN socket pin information
to ensure correct polarity. If a +12 V power supply is
accidentally connected to the GND terminal, this could
cause a fire or personal injury.

NOTE
When both the battery and the external DC power supply are
connected, power is supplied from the external DC power
supply. The battery can be removed or mounted while using
an external DC power supply.
When using an external DC power supply, make sure you
turn on the external DC power supply before turning on the
camera-recorder’s power switch. If this sequence is reversed,
the camera-recorder may malfunction due to slow rising of
the external DC power supply voltage.
To connect a battery to the DC IN connector, select BATTERY
in the menu option EXT DC IN SEL, and select the battery
type in the menu option BATTERY SELECT in the BATTERY
SETUP screen. Note that with these settings, the “%”
indication cannot be displayed, even for batteries capable of
indicating remaining power.
