9. Backlight and Child Lock

9.2. Child Lock Function
The child lock feature prevents accidental changes to settings. To activate or deactivate the child lock, slide the dedicated switch to the "ON" or "OFF" position. When "ON", the time display and buttons will be deactivated to prevent unintended adjustments.
