I see
Press the button on your Square Reader once to see the battery level.
Could you please tell me what lights do you see?

Great, thank you
Please reset your square reader.
Hold down the power button for approximately 20 seconds. The lights on your reader will flash orange, then red, and then they will stop flashing. Do not let go of the power button until after the red lights have stopped flashing.
