            Note: A total of 127 memory address settings are available.
            The switches are a binary representation of the hexadecimal
            memory addresses. SW1/7 is the Most Significant Bit and
            switch SW1/1 is the Least Significant Bit. The switches have
            the following hexadecimal values: SW1/6=200h, SW1/5=100h,
            SW1/4=80h, SW1/3=40h, SW1/2=20h, SW1/1=10h. Turn off the
            switches and add the values of the switches that are off to
            obtain the correct memory address. (Off=1, On=0)
