Regarding external DC power supply
Connect after making sure that the output voltage of the external DC power supply is compatible with the rated
voltage of the device.
Select an output amperage for the external DC power supply with a margin above the total amperage of the
connected devices.
The total amperage of connected devices can be calculated with the following formula.
Total power consumption
÷
voltage
When the power of the camera is turned on, inrush current is generated. Insufficient power supply when turning
on the power may cause a malfunction. We recommend that you use an external DC power supply that can
assure double the capacity of the total power consumption of this device and connected devices that are turned
on by interlock when the power of the device is turned on (such as lenses). For the DC cable, use a dual-core
shielded wire of AWG16 (nominal cross section area 1.309 mm
2
) or thicker.

Make sure of the pin alignment of the DC output terminal of the external DC power supply and the <DC IN>
terminal of the device, and connect the polarity correctly.
Making the mistake of connecting a

12 V power supply to the GND terminal may cause fire or malfunction.

NOTE
t
When both the battery and the external DC power supply are connected, the power supply from the
external DC power supply has priority. The battery may be removed while using the external DC power
supply.
t
When using an external DC power supply, always turn the power switch of the external DC power
supply on before setting the <POWER> switch of the recording module to <ON>. If the operations are
performed in reverse, the camera may malfunction because the external DC power supply output voltage
rises too slowly.
t
When switching the power supply from an external DC power supply to the battery, carefully remove the
DC cable from the <DC IN> terminal. Removing the cable quickly may temporarily stop the operation of
the device.
t
When power is supplied from the <DC IN> terminal, the light circuit does not function. The light circuit
can be used only when power is supplied from the Anton/Bauer battery plate.
t
When a battery is connected to the <DC IN> terminal, set [MENU]
→
[SYSTEM SETTINGS]
→
[BATTERY]
→
[CAM EXT DC IN SEL] to [BATTERY], then set [CAM BATT END], [CAM BATT NEAR
END], and [CAM BATT FULL] according to the features of the battery. The percent (%) display will not be
available for batteries with a battery level indicator function.
