How do I set the memory on my Feather-Lift™ control paddle?

There are two groups of memory settings, each with two height settings. To toggle between the two users, momentarily press the M button and display will read U1 or U2. Up to four memory stop positions can be used to save specific heights of the work surface. To set a specific position: Raise or lower the table to the position you want to save. Press and hold the M button for two seconds, the LED will blink.  This means it has stored the location.
