   |     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)                                            |
