Please note, the connection cable is not included. There's a known issue: there's a loose piece rattling inside the unit.

Using this Hitachi remote control unit for your HD color camera system is easy. Just point it at the camera and use the buttons to control functions. Note that it doesn't come with a connection cable, so you'll need to get one separately. Also, there's a loose piece inside that makes a rattling noise, but it shouldn't affect normal use. To maintain it, keep it in a dry and clean place. Avoid dropping it or exposing it to extreme temperatures. If you have any further problems, contact Hitachi customer service.
