P/Y), press & [, key in a number,
and press !. To change the compounding periods (C/Y), press & [
#, key in a number, and press !.
• To change the payment period (END/BGN), press & ], and then press
& V.
• To compute a value for the unknown variable, press C, and then press
the key for the unknown variable.
