CS-800 MANUAL 3 - Software Specification 3.1 Pairing 3.1.1 Pairing Condition RCU can perform pairing with 1 Sound Bar. 3.1.2 Pairing (Re-pairing) Scenario Press and hold the BT button on the Sound Bar Sound Bar LED will indicate RCU pairing mode, like flashing blue. Press the RCU [Enter OSD Menu] or [Exit OSD Menu] Button for about 3 seconds to start pairing. i. If the previous pairing information remains. 1. Send un-pairing command to the Sound Bar. 2. Delete the pairing information and start pairing. After pairing starts, advertise until Advertising Time Out. ii. 1. Advertising Time Out is about 30 seconds. 2. Advertising Interval is about 30 ~ 35ms. When the Sound Bar find the new RCU, deleting the previous pairing information and pairing with the new RCU. When pairing is complete, all buttons of the RCU output RF code. 3.1.3 Reconnection (Disconnected State) After pairing, when the power of the RCU is re-applied or the BLE connection between the Sound Bar and the RCU is disconnected, it advertises every 5 seconds. When the BLE connection is disconnected, Press any RCU button to start direct advertising for 5 seconds to reconnect. 3.1.4 Factory Reset When reconnection is completed, all buttons of RCU output RF Code. Press about 5 seconds [Power] + [] Button, try the Factory Reset. In case of Factory Reset, the BLE connection between the Sound Bar and RCU is disconnected. And the pairing information of the RCU is also deleted. The RCU sends an un-pairing command to the Sound Bar before deleting the pairing information. Sound Bar receives the Un-Pairing Command Code, it deletes the pairing information.
