TWS connection:
2.1. When the new machine is dual-connected for the first time, you need to long press the TWS button for both machines, when you hear “Di* it means pairing is in progress.
When the pairing is successful, you will hear “Di Di”. (under normal circumstances, the pairing is successful within 6 seconds, but the greater the environmental interference, the longer the pairing time)
2.2. tf the two devices have been connected, turn off and on again, the machine will automatically interconnect, no need to re-connect.
2.3. TWS is disconnected or reconnected, the host needs to be operated (the host means: the one that can be controlled by Bluetooth is the host, and the one that needs to be paired is the slave). -
Other connections: The machine automatically detects and recognizes the external device when it is turned on, and enters the wireless connection AUX mode after it is turned on. The TF card or USB is inserted and automatically recognizes the playback.
The latter has the priority principle, and the playback mode can also be switched by itself; the audio signal line does not switch automatically, just shut down and restart.
