Repair your Logitech Harmony 720 to continue one-touch control. Harmony remote controls provide one-touch controls by establishing "Activities" that send multiple commands with the touch of one button. The remote is programmed using a computer and allows for customisation of how to control your home theatre system. The Harmony 720 remote can have issues in regard to charging the batteries, controlling devices and others. Most of these problems can be repaired without needing a technician.
Charge the battery for three hours to allow the remote to get a complete charge if the remote is not powering on. Update the firmware by launching the Harmony Remote software. Click on the "Start" button, select "All Programs" and then click the "Logitech" icon. Connect the USB cable to the computer and the Harmony 720. Click on "Downloads" and then select the "Firmware" button. Click the "Update Remote" button once the firmware is downloaded.
Replace the batteries if they are not holding a consistent charge. Push down on the bottom of the remote to remove the battery cover. Remove the defective battery from the remote and insert the new battery in its place. Put the battery cover on the remote and charge the remote for three hours.
Adjust the command delays if the activities are not working correctly. Click on the "Start" button, select "All Programs" and then click the "Logitech" icon. Click on the "Devices" tab and select the "Settings" option next to any device that is giving problems with the controls. Select "Adjust the Delays" and increase or decrease the speed of the commands. Allow the software to complete a check of the activities and then update the remote to complete the changes.
