2. Set the machine type and number using the DIP switch on the MCU circuit board:
   See DIP switch settings page to understand how to configure DIP switch positions to set the machine type (washer or dryer) and number. Note that MCUs may already come from Mitech configured with the appropriate DIP switch settings. Proceed with installing the MCU on the corresponding machine type and number.
