            Note: A total of 64 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. SW1/1 is the Most Significant Bit and switch SW1/6
            is the Least Significant Bit. The switches have the following
            decimal values: SW1/1=512, SW1/2=256, SW1/3=128, SW1/4=64,
            SW1/5=32, SW1/6=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)
