Note: A total of 512 sounds are available. The switches are a binary representation of the decimal sound addresses. SW1/2 is the Most Significant Bit and switch SW1/10 is the Least Significant Bit. The switches have the following decimal values: SW1/10=1, SW1/9=2, SW1/8=4, SW1/7=8, SW1/6=16, SW1/5=32, SW1/4=64, SW1/3=128, SW1/2=256. Turn off the switches and add the values of the switches that are off to obtain the correct sound. (Off=1, On=0)
