Turning off the four beeps when start cutting?

Hi,
When the roboticmower is on a task to cut the lawn and is transporting itself between areas to cut, the cutting disc stops to spin. When the mower starts to cut again it beeps four times. This is annoying, and I guess that the neighbours thinks the same... but no complaints yet.
I have turn the voice volume all the way down, but I don't see any options to turn the beeps off. How do I turn it off?
Thanks!

Hola, pero los 3 pitidos son muy bajos y casi no se oyen , es muy silencioso. Es un aviso que baja las chucillas.

Bonjour
J ai deux zones dois je creer deux chemins vers la station ?

Hello,
For safety reasons, we designed the robot to make a "beep, beep, beep" sound to remind the user that the cutter has started. This sound cannot be turned off for the time being.
