How do I change the auto-standby (auto-off) time on the machine?

Press and hold the power button for approximately 5 seconds until 1 beep is heard — one coffee button will light up continuously indicating the current setting, while the other two flash. Press the espresso button for 10 minutes, the caffè crema button for 20 minutes, or the americano button for 30 minutes to set your preferred auto-off interval.
