The eight registers on the right side of the calculator display are the
memory registers. These registers allow you to manually store and recall
constants or set aside numbers for use in later calculations. Values
placed in the top four memory registers (5 - 8) are retained even when
the unit is powered down. Values in the lower four registers (1 - 4) are
cleared automatically when you exit from the calculator function.
