The Harmony one is always learning new tricks!
Maintaining your Harmony 555
Your Harmony 555 contains internal software, called firmware. The remote’s firmware is similar
to your computer’s operating system.
Logitech updates the firmware for your remote to ensure you’re always getting the most from your
Harmony 555. Generally, when you connect your remote to your computer the Harmony Remote
Software updates your remote automatically if new firmware is available.
However, sometimes you may need to update the firmware manually.
To upgrade your Harmony 555 firmware:
Connect your Harmony to your computer using the USB cable.1.
Start the Harmony Remote Software.2.
Click 3. Downloads.
Click 4. Firmware.
Follow the online instructions.5.
Upgrading your Harmony 555 firmware
After you finish making any changes to your Harmony 555 configuration, you should test the new
set up to ensure everything is working the way you expect. This testing process is the same as the
one you did when you set up your Harmony 555 for the first time. For more detailed information,
see Testing your setup.
Testing your remote settings after a software upgrade
When you upgrade to a newer model Harmony, you can transfer the configuration from your old
remote to your new remote.
To upgrade to a new model Harmony remote:
From the Harmony Remote Software:
Click 1. Remote Settings.
Click 2. Manage Remotes.
Click 3. Replace.
Follow the online instructions.4.
