3) Press [2ND] [SET] again to return the setting to end-of-period payments. END is displayed.
4) Press [2ND] [QUIT] to exit.

To change P/Y (payments per year) and C/Y (compounding periods per year):

1) Press [2ND] [P/Y] to display the P/Y worksheet. (Resetting the unit sets the P/Y to 12 on the BA II PLUS and 1 on the BA II PLUS PROFESSIONAL).
2) To change the value, key in a new value and press [ENTER]. 
3) Press the down arrow to display the current value for C/Y. C/Y is the same value as P/Y unless it is changed separately.
