Chapter 5 Preparation Use of the external DC power supply 1 Connect the external DC power supply to the DC IN socket on the unit. DC IN Socket External DC  power supply DC cable 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 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. • W hen 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. 1 2 4 3 Pin No. 1 2, 3 4 Signal GND - +12V  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. 88

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.
