When using USB as the audio source, the "What's playing" display at the lower left corner of the display does not show the 3 equalizer bars to click on to adjust the tone. So there is no path to the 3 bars as described in the manual.
Swipe down on "what's playing" and it not only disappears from the lower left corner, the whole "what's playing" appears at the top of the USB screen and with the 3 bars and you can go adjust the tone.
