Walk through our setup tutorial: adding your home entertainment devices, setting up a one-touch Watch TV Activity and learning more about the usage of your remote. Already set up and something's not working? Our troubleshooters and support articles will help set things right.
Lets get started.
Your Harmony 300 allows you merge the remotes of up to 4 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.
Harmony 300 remote enables one-touch Activity based control of your home entertainment system.
Two AA batteries come included with your Harmony 300. Remove the back battery cover and insert the two AA batteries into the remote.
Your new remote is configured by connecting your Harmony 300 to your laptop or desktop computer using the supplied USB cable, and signing in to the MyHarmony desktop software.
Download and install the MyHarmony desktop software.
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.
Ensure you've installed the two AA batteries into the back of your remote.
Using the supplied USB cable connect Harmony 300 to your computer.
If this is your first remote then you'll be prompted to enter the manufacturer and model for each of your home entertainment devices.

Are you upgrading an existing Harmony remote? You may also choose to import your previous remote settings.
Once all your devices have been entered, the MyHarmony desktop software will prompt you to create a Watch TV Activity.

If one of your devices didn't power on or change to the correct input, then we recommend using our Activity troubleshooter to help narrow down the problem and find a solution.
