Note:

A total of 64 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/6 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/6=256, SW1/5=128, SW1/4=64, SW1/3=32, SW1/2=16, SW1/1=8. Turn off the switches and add the values of the switches, including an additional value of 512 as a fixed setting, to obtain the correct memory address. (Off=1, On=0)
