IRR Problem on my new 10bII

I am facing problem with the calculation of IRR on my new 10bII.
The IRR computation is wrong.
To compute IRR of the following cash flows: - -11 + 12 / ? Where NPV is 0
The process I keyed in is

Shift clear all
11 (+ / -) CFj
12 CFj
Shift IRR / YR

The answer I get now is 109.0909

This is obviously wrong. I used to get 9.0917 percent.

Can you kindly advise?

Answer:

Hi Brian,

You need to set the P / YR to 1. The default is 12.

1 Shift P / Yr

Shift c all "Screen should display 1"

11 (+ / -) CFj

12 CFj

Shift IRR / YR  "Screen should display 9.0909"

Here is a primer to setting up your HP 10bII.

    Why do I keep getting "No Solution"? Solving for interest rate:
    PV=0
    FV=801,455
    N = 20 (annual)
    PMT = 40,000
    Appreciate the help. Using HP10BII+

      You got to enter a negative value for PMT. Enter 40000 then press the [+/-] key.
