TVM and example in User Guide

[salvomic]

hi,
with the example of page 292 in User Guide, I'm calculating the Amortization, but I get something different from that example (next page).
i.e.
I get (now with FW 7820):
P Principal Interest Balance
1 -1676.57 -9700.63 148323.43
2 -1788.85 -9588.35 146534.58
...
The example has:
P Principal Interest Balance
1 -1676.57 -9700.63 148323.43
2 -3465.42 -19288.98 146534.58

Is it a different mod of calc for amortization? or the values for TVM were different from those printed?

I would like to know more about the guidelines in Finance App...

Thank you,
Salvo
