Hi everyone! I know that I can check the battery level by pressing the HELP button, but this only works when the OP-1 is turned on, not while it's charging. When I charge the OP-1, the battery LEDs all light up one after another, even if I've just started charging, and it was empty. It always goes through all 5 LEDs, including the red one. How do I know when I can disconnect the cable?
Any help is much appreciated! :)
