Using this remote is easy. First, insert 4 AAA batteries (not included) into the battery compartment. Then, follow the simple setup instructions which should take less than 30 seconds to pair it with your TV. You can control various functions of your TV, LCD, or Plasma set. When it comes to maintenance, keep the remote dry and clean. Avoid dropping it or exposing it to extreme temperatures. If you find that your TV model isn't supported, head to the One For All website and download the extra codes.
