How to Control a Samsung HW-C450 Soundbar With an AT&T U-Verse Remoteby Jason TaetschUpdated September 28, 2017
The remote included with your AT&T U-verse receiver can control a number of devices so you can turn on your TV, receiver and sound equipment from one remote. Program the remote to your Samsung HW-C450 sound bar so you don't have to juggle multiple remotes every time you watch TV. The remote features a built-in code search option that automatically pairs the remote with a device.
Turn on the Samsung sound bar.
Point the remote at the device and press the "AUX" button. Press and hold the "OK" and "AUX" button. The buttons at the top of the remote will blink twice.
Press "9" "2" "2." Press the "Play" and then the "3" key. The "Aux" button will blink twice. Press the "PLAY" button repeatedly until the sound bar turns off. Press "Enter" to save the code and complete the programming of the remote to your sound bar.
