No audible alarm on Horsch Drill Manager V24

[horizontal]

I bought a 2005 Horsch Sprinter earlier this year but there is no audible alarm when the low bin sensor or any other sensor activates. Does anyone know if there is a sequence to activate or deactivate audible alarms or is it possible the audible alarm just isn't working (message alarms appear fine on the screen)?

Give Horsch Uk a ring. Their field engineeers are very helpful and knowledgeable from my experience.
