Checking the Level of the Batteries in the MB-N14
When the MB-N14 is connected and the camera is on, the level of the battery currently providing power to the camera is shown in the camera’s shooting display and control panel.
The chamber containing the battery currently in use is indicated by an icon next to the battery indicator in the camera’s shooting display.
Additional information, including the battery age and precise battery level, can be viewed using the [Battery info] item in the camera setup menu.
