When connecting four or more Bluetooth devices to the TV, the connection or pairing may fail.
Turn off any Bluetooth devices that you are not using, or cancel the pairing by another method, and then connect the desired Bluetooth device again.
Bluetooth devices use the 2.4GHz band, therefore communication speed may deteriorate or cut out occasionally due to wireless LAN interference. If household electric appliances (e.g. microwaves or smartphones) are placed nearby, radio wave interference is more likely to happen.
The TV or device may not work on a metal rack due to wireless communication interference.
