Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth BT Error Fix: Bluetooth Mode Active

Error code BT on the Samsung TV & Audio HW-S800B Ultra Slim 3.0 Channel 360 Watt Soundbar with Dolby Atmos and Bluetooth means: Bluetooth Mode Active. Display shows "BT" — soundbar is in Bluetooth mode and connected to a device. If no audio plays: check the connected device is actually streaming, volume is up on both soundbar and source device, and the correct Bluetooth device is connected (soundbar may auto-connect to the last paired device). If audio is choppy or cutting out, move the source device closer (within 30 feet line-of-sight), reduce interference from other 2.4 GHz devices (Wi-Fi routers, microwaves, baby monitors). Samsung soundbars support SBC and AAC Bluetooth codecs — audio quality depends on source device codec support.
