How do I program custom shot volumes on the Bambino Plus?

Press and hold the 1 CUP and 2 CUP buttons simultaneously for 2 seconds until the buttons illuminate and flash. To set the 1 CUP volume, press the 1 CUP button to start extraction, then press it again to stop — the modified volume will be saved. Follow the same steps using the 2 CUP button to set the 2 CUP volume. (Page 12)
