SOURCE: incorrect claculation
I get an answer of 366.91 in my 12C as well. You might try either putting in a zero for FV before hitting the [PMT] key, or clearing your registers before doing the problem, as you may be picking up an old value from a previous problem in the FV register.

Resetting the Calculator
If the calculator doesn't respond to keystrokes or if it is otherwise behaving unusually, attempt to reset it. Resetting the calculator halts the current calculation and cancels program entry, digit entry, a running program, a SOLVE calculation, an ∫ FN calculation, a VIEW display, or an INPUT display. Stored data usually remain intact.
To reset the calculator, hold down the C key and press GTO . If you are unable to reset the calculator, try installing fresh batteries. If the calculator cannot be reset, or if it still fails to operate properly, you should attempt to clear memory using the special procedure described in the next section. If the calculator still does not respond to keystrokes, use a thin, pointed object to press the RESET hole.
The calculator can reset itself if it is dropped or if power is interrupted.
CLEARING the MEMORY
If the calculator fails to respond to keystrokes, and you are unable to restore operation by resetting it or changing the batteries, try the following MEMORY CLEAR procedure. These keystrokes clear all of memory, reset the calculator, and restore all format and modes to their original, default settings (shown below):

Welcome to FixYa!
Here's a list of things to do if your HP49G calculator does not turn on.
1. Replace the batteries. (which you have done already)
2. Press and hold "ON" then press "+" several times, then release "ON".
If chacracters still doesn't appear in the main screen, reset the calculator:
1. Press and hold "ON" then press "F3", then release both keys.
The calculator should reset. If not:
1. Insert the of a metal paper clip into the hole at the back of the calculator. Insert as far as it goes. Hold for 2 seconds then remove the clip.
2. Press "ON".
If that does not fix the problem, the calculator needs to be serviced.
Note: always use alkaline batteries.
I hope this helps.
Thank you for using FixYa!
Keep me posted.
