The alarm doesn't actually stop when it's left alone for 3 minutes. Like most alarm clocks, the Mudita Bell and Bell 2 have a snooze feature.
Automatic Snooze
Snooze will trigger automatically if the alarm rings and the user does not interact with the device within 3 minutes. After another 10 minutes, the alarm will start ringing again.
This process will repeat 3 times if the user still doesn't interact with the clock. After 3 automatic snoozes, the alarm will finally stop ringing.
Control Snooze Manually
The user can also manually activate snooze by light-clicking or twisting the main knob on the top of the clock.
The snooze time is always 10 minutes and cannot be changed by the user.
