Hi PJ,
Follow the instructions below on how to set your Spectrum Remote up to control your Soundbar. Make sure that your TV speaker is set to External Speaker.
1. Turn Off the Soundbar.
2. Push up and hold the WOOFER button for 5 seconds.
Each time you push the WOOFER button up and hold it for 5 seconds, the mode switches in the following order: “Off-TV Remote” (Default mode), “Samsung-TV Remote”, “All-TV Remote”.
The LED indicator status changes each time the mode is changed. Refer to page 17 of the full manual for more detailed instructions.
