•In the SD Mode and REG Mode, the key operates as the Skey.

•Always start data input with AB1(Scl) =to clear statistical memory.

•Input data using the key sequence shown below. <x-data> S

•Input data is used to calculate values for n, Σx, Σx2, o, σn and σn-1, which you can recall using the key opera- tions noted nearby.
