What menu option do I have to select in order to find the following?
- Firmware installed on the camera;
- Current setup (including customized selection);
- # of recording hours don with the camera...

Thanks in advance!

Operation time is displayed in 10 hour increments in the OTHERS menu on the HXR-NX5U.
