Understanding how Harmony works

Your Harmony 350 allows you merge the remotes of up to 8 of your home entertainment devices into one so you can, and should! keep those other remotes out of sight.

The MyHarmony desktop software will guide you through entering the manufacturer and model numbers of your home devices so Harmony understands how to control them. It then helps you create your Watch TV Activity (or scene) so you're only one-button away controlling your devices.

Let's get started

What's in the box

Harmony 350 remote

Two AA batteries

Two AA batteries come included with your Harmony 350. Remove the back battery cover and insert the two AA batteries into the remote.

USB cable

Your new remote is configured by connecting your Harmony 350 to your laptop or desktop computer using the supplied USB cable, and signing in to the MyHarmony desktop software.

Adding Devices and Activities

  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 Harmony 350 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.

    Learn more about finding your device's model number.

    Are you upgrading an existing Harmony remote? You may also choose to import your previous remote settings.

  5. Once all your devices have been entered, the MyHarmony desktop 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 video and hear sound. Follow the on-screen instructions, or learn more about creating a Harmony Activity.

  6. That's it! Click the Sync button to transfer these settings to your remote.
