Getting Started with your Harmony remote

  1. Download and install the Harmony software.
  2. If this is your first Harmony remote, create a new account. If you already have a MyHarmony account then you may sign in and add this new remote to your account.
  3. Ensure you’ve installed the two AA batteries into the back of your remote. Using the supplied USB cable connect the Harmony to your computer.
  4. If this is your first remote then you’ll be prompted to enter the manufacturer and model for each of your home entertainment devices.
  5. Once all your devices have been entered, the Harmony software will prompt you to create a Watch TV Activity. You’ll be asked what input each of your devices have to be on in order for you to see the video and hear the sound. Follow the on-screen instructions.
