A. Learning Pairing Code: After powering on, quickly double-click the S1 button. The work indicator light will start flashing, entering the setting mode. In this mode, triggering any button on the remote control will cause the work indicator light to light up for about 1 second, indicating successful pairing. After pairing is complete, wait 10 seconds without any remote control activity, then automatically time out. B. Clearing All Remote Controls: After powering on, press and hold the S1 button for more than 8 seconds, then release the button to clear all learned pairing codes.
