If the PC is turned off, the power to BA11 is terminated, which cuts the Bluetooth connection.
When the PC is restarted, the connection is not restored automatically. However, pressing the Trigger Switch of AT10Q-SB re-establishes the connection.
The above description also applies to AT27Q-SB, SE1-BB, SE1-QB, and WS1-QB.
If “Easy connection setup” has been performed, when the PC has been restarted, pressing the Trigger Switch automatically restores the connection.
