There are two ways to lock on the buttons and upper metal cover so the light and sound of the machine will not be changed by pressing the buttons.
On the machine
Long-press the "Play/Pause/Chile Lock" button for at least 3 seconds to lock on the buttons and upper metal cover.
In the app
Tap the "Child Lock" option in the app to lock the buttons and upper metal cover.
Verify the lock-on
The three lights at the back of the machine will flash slowly and simultaneously, it means that the upper metal cover and buttons are locked on successfully.
