100 Preparation Power Supply1 Connect the external DC power supply to the DC INsocket on the unit.2 Turn “ON” the power switch of the external DC powersupply. (If the power switch is available on the externalDC power supply)3 Turn ON the POWER switch on the unit.Notesz If both the battery pack and the external DC powersupply are connected, the electric power is suppliedfrom the external DC power supply. While theexternal DC power supply is used, the battery canbe mounted and removed on/from the unit.z When the external DC power supply is used, ensurethat the power switch of the external DC power supplyis turned on first and then the POWER switch on theunit is turned on. In the case of the reverse operation,a malfunction may occur on the unit since the outputvoltage of the external DC power supply is raisedslowly.Use of the external DC power supplyDC IN SocketExternal DCpower supplyInrush current is generated when the power of the unitis turned on. Insufficient power supply when turningon the power may cause a malfunction. We recom-mend using an external DC power supply with doublethe capacity of the total power consumption of the unitand any other connected device that is turned by inter-locking with the power on of the unit (the viewfinder).Select the DC cord that is recommended for the exter-nal DC power supply.Confirm the pin arrangements of the DC outputconnector of the external DC power supply and theDC IN socket on the unit, and connect the properpolarities to each other.If the +12 V power supply is connected to the GNDconnector in error, it may cause a fire or failure ofthe unit.12 34Pin No. Signal1 GND2, 3 —4 +12VDC IN Socket
