What does the white indicator light on the A2+ Wireless rear panel mean?
If it's on and solid, this means the A2+ Wireless is powered on, and currently connected to a Bluetooth-enabled device.
If it's on and blinking, this means the A2+ Wireless is powered on but not currently connected to a device.
If it's off (and A2+ Wireless is powered on), this means Bluetooth is in standby and not connected to a device. The A2+ Wireless, however, is still visible to your device, so simply connect using your device and it will automatically wake up.
