Using the JVC RM - HP250 camera remote control unit is easy. First, make sure the power supply is correctly connected. Then, turn on your camera and the remote control. You can now use the remote to take pictures or start/stop video recording from a distance. When not in use, store the remote control in a dry and cool place. Keep it away from water and extreme temperatures. If the remote control isn't working properly, check the power supply and make sure the batteries are in good condition. Replace the batteries if needed.
