STEP 1: Press any of the four control buttons for two seconds to power on the device. When the LEDs come on, release the button.
NOTE: If the One does not power on, charge your device for at least four hours and then try again.
STEP 2: Immediately power down the One by simultaneously pressing the Alt and Minus control buttons for two seconds. When the LEDs shut off, release the button.
As the device is powering down, the battery level will flash across the 0-10 scale.
The point at which the LED stops flashing prior to shutting down is the current battery level.
The further to the right at which the LED stops flashing, the more power the battery has. The further to the left the LED flashes, the closer to depletion the battery has become.
