To change the alarm tone, volume, and alarm backlight settings on your Bell, press the "Settings" button (top-left with the cog icon) and hold it down for at least 2 seconds. The clock will then enter the three-step alarm settings mode.


  • Choose the alarm melody
    First, you will be able to choose the sound of the alarm out of 10 available options. Twist the main knob on top of the device left and right to navigate between the different available sounds. When you find the one that you'd like to use, light-click the main knob to select the one that currently plays. The clock will then automatically move on to the second step.

  • Adjust the alarm volume
    After choosing the alarm sound, you can change the volume, at which you would like it to play. Rotate the main knob to adjust the volume. Once you find the level that suits you, light-click the main knob to confirm your choice.

  • Enable or disable alarm light
    The Mudita Bell can turn on its backlight when the alarm is ringing. Twist the main knob right to activate this feature or left to turn it off. Light-click the main knob to confirm your choice when the light is shining or not.
