To use this Hitachi remote control panel, first make sure your HDTV camera system is compatible. Simply turn on the camera system and then the remote control panel. You can then use the buttons on the panel to control different functions of the camera. When it comes to maintenance, keep the panel in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If the panel doesn't work properly, check the batteries first and replace them if needed. Also, since there is no connection cable included, you'll need to use your own compatible cable for the connection.
