I just charged my jewelbot. When I press the magic button a red light appears and then goes away. If I hold down the button for 5 seconds all four lights flash blue and does not stop. If I hold the button down for 5 more seconds, the lights stop. I am really confused because according to the instructions I should see a rainbow when I press once to tuun it on and see the same when press it for 5 seconds to turn it off.
