Charging the Battery Use a Car's Cigarette Lighter Socket to Recharge the Battery With Car Battery Cable CB-570 (sold separately), you can connect the charger's car battery cable socket ( terminal) to your car's cigarette lighter socket. When recharging the battery this way, be sure that the car's engine is running. Disconnect the car battery cable from the cigarette lighter socket when the car engine is off. If you leave the car battery cable connected to the cigarette lighter socket, it may drain the car battery. Do not use a transformer for the car with the battery charger. Battery charging from a car battery is possible only with a 12 V DC or 24 V DC car battery in a minus-grounded car. The shape or dimensions of the cigarette lighter socket in certain cars might not be compatible with the car battery cable. The Lamp Blinks in Red This indicates that you should calibrate the battery so that the correct battery level is detected and the camera's battery level indicator can display the correct battery level. Calibration is not a required operation. If you just want to recharge the battery, you can let the battery start recharging automatically after approx. 10 sec. If you want to perform calibration, press the button while the lamp is blinking in red. The Charge level indicator will blink in red and calibration (power discharge) will start. After calibration is complete, the battery will start recharging automatically. Note that the less depleted the battery is the longer calibration will take. The , , and figures on the side of the Charge level indicator indicate the approximate time it will take to complete calibration (power discharge). If the indicator blinks in red, it will take approx. 10 hours. After calibration is complete and the battery is totally drained, it will take a further 2 hours to recharge the battery fully. If you want to stop calibration before it is completed and start recharging the battery, remove the battery from the charger and attach it again. 32
