Step 1: With the power turned off, open the back panel over the
Control Unit. Loosen the two thumb screws on the panel and
rotate the panel on its hinges.
Step 2: Replace the EEPROM on the Control Unit board. You will
need to use bent-nose pliers to properly remove the EEPROM.
Step 3: Install the new EEPROM making sure the small indentation
on the top is to the left side. This ensures proper polarity.
Close the back panel and tighten the thumb screws.
