I recently purchased the B&O F3 dealer appreciation set, 20-80004a.
I replaced the white battery with a green nimh battery. I externally charged it. My problem is that the sounds are real low and somewhat garbled. The “info” screen in DCS also shows low battery even though I know it’s not. Everything else works fine, smoke, cruise, couplers. It’s just the low sound and low battery. I did try a new 9v battery and there is no difference
Any ideas would be much appreciated.
