With TVM Canada enabled in the Mode menu, the following TVM features change:
1. The P/YR key,
:[
, now opens a menu with two items, P/YR and C/YR, in which you can specify the
number of payments and compounding periods per year. Press
<
or
>
to scroll through the menu. See
Figure 4.
2. To change the value of an item, with the item displayed, enter the number desired followed by
I
.
3. In the Interest Conversion menu, the C/YR item has the same value as the C/YR item in the P/YR menu, and
C/YR and no longer affects P/YR.
4. Note, however, if you now change the value of P/YR, the calculator automatically sets C/YR so it equals your
new value assigned to P/YR. This means that if you modify P/YR, you also need to modify C/YR, if P/YR and
C/YR are different values in your TVM problem.
