Here is how you can adjust the alarm melody and volume and control whether or not the clock face will light up during the alarm.
Alarm Settings
To enter the alarm sound settings, press the melody button and hold it down for at least two seconds, until the first sound starts playing.
You can then move between the different alarm sounds with short clicks of the melody button and rotate the main button to adjust the volume level.
To select an alarm sound, press and hold the melody button for at least 2 seconds when your chosen sound is playing.
If you don't interact with the clock for 60 seconds, it will also select the currently playing alarm sound and exit the settings.
There are nine alarm sounds to choose from. Click here to see the list of available sounds and listen to each one.
Enable or Disable the Alarm Light
To turn on the light when the alarm goes off, use a long press on the light button for at least two seconds. Then the light will turn on. To turn the light on and off, rotate the main knob. To save changes, use a long press on the button again. Changes will automatically be saved after five seconds without interaction.
When the alarm light comes on, it will get progressively brighter with time, until it reaches its maximum brightness. The light will start shining first and the alarm sound will play within about a minute.
To adjust the general light intensity (not for the alarm light), rotate the main button while the light is on.
