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