Introduction The step-down voltage converter reduces voltage from a 9-25V DC power source down to 7.2-7.4V. The LED voltage indicator helps in monitoring the battery status.* Operation 1. Plug the camera DC cord into the output jack. 2. Connect the converter to the DC power source using either 4-pin XLR connector or the DC jack. 3. Operate the camera in the usual manner. 4. Periodically monitor the DC Converter's LED.
