If you are experiencing any issues with your remote control, head over to the Logitech Harmony 300 Troubleshooting page.
The Logitech Harmony 300 is an universal remote controller manufactured by Logitech. Released in April 2010 in two different versions, the remote control comes as a Harmony 300 matte black finish and as a Harmony 300i glossy black finish.
Geared towards the low-end affordable universal remote controllers, the Harmony 300 has the ability to program 4 different devices by using the MyHarmony application downloadable online. Other features include the ability to program up to 5 different channels and program one activity to start two devices at once.
The Logitech Harmony 300 has since been discontinued but has been followed by the Logitech Harmony 350 (May 2014) which has the ability to control up to 8 different devices with an almost identical button layout to the Harmony 300.
