Hi, I have just fixed my CCC professional head unit after blowing the power board. See link below for details:

My problem is that now I have swapped the power board, the volume of the warning chimes for low fuel, lights left on or handbrake not fully release etc has increased to a ridiculously loud level.
Can anyone help me lower the volume of the chimes. I’m happy to get the unit recoded or open up the head unit and change another board or component I just need a steer in the right direction.
