2. Press ´U to activate User mode.
3. If necessary, press ´CLEARQ to clear all of the financial variables. You don't
need to clear the registers if you intend to specify all of the values.
4. Set flag 0 according to how payments are to be figured:

Press |"0 for payments at the end of the period.

Press |F0 for payments at the beginning of the period.
5. Enter the known values of the financial variables:

To enter n, key in the value and press A.

To enter i, key in the value and press B.

To enter PV, key in the value and press C.

To enter PMT, key in the value and press Á.

To enter FV, key in the value and press E.
6. Calculate the unknown value:

To calculate n, press A ¦.

To calculate i, press B ¦.

To calculate PV, press C ¦.

To calculate PMT, press Á ¦.

To calculate FV, press E ¦.
7. To solve another problem, repeat steps 3 through 6 as needed. Be sure that any variable
not to be used in the problem has a value of zero.
