To use this Vaddio ProductionVIEW Precision Camera Controller, you'll need to connect it to an external power source as it doesn't come with a power supply. First, make sure your power source matches the controller's power requirements. Then, connect the controller to your camera according to the standard connection methods. When you're using it, don't be bothered by the rattling sound inside, as it won't affect how well the controller works. For maintenance, keep it in a dry and clean place. Periodically check the connection cables to ensure they're in good condition. If you have any further questions, feel free to seek professional help.
