Using Numbered Registers: The (OS) (STO) and (RCL) keys access the 10 user registers. The
(OS) (STO) key is used to copy the displayed number to a designated register. The (RCL) key is
used to copy a number from the register to the display.
Storing and recalling numbers requires two steps:
1. Press (OS) (STO) or (RCL). To cancel this step, press (? ) or (C).
2. Enter the register number (0 through 9).
Example: In the following example, two storage registers are used. Calculate the following: 475 ÷ 39
and (560 + 475) ÷ 39.
