Hi chen! Plug the SWA-9500S power cord into an outlet and into the speakers to turn them on. Turn off your soundbar and press the Up button on the remote for 5 seconds. The ID SET message will appear on the soundbar for a short time and then disappear. After the ID SET process, the soundbar power is automatically turned on. The LINK LED indicator stops blinking and glows a solid blue when a connection is established between the soundbar and the rear speakers. Should you need additional assistance with the pairing process, please contact us at 1-800-SAMSUNG, available 8AM - 12AM EST, 7 days a week, or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/ ^Tim
