The 2nd indicator light on your headset base is your Bluetooth mode light!
If it’s flashing blue, your Leitner base is trying to pair to a Bluetooth device.
If it’s a solid blue, it’s paired to a Bluetooth device!
Note: When you put the headset on the charger, the blue light will disappear, but will re-light when picked back up.
That’s it! The end :)
