The language and camera clock have reset

The language and camera clock will reset if the camera is left for an extended period with an exhausted battery. Insert a fully-charged battery into the camera, then reset the language and camera clock.

Camera Clock

The camera clock is powered by an independent clock battery. The clock battery charges when the main battery is inserted in the camera; fully charging it may take a few days. Once charged, it will power the clock for several months. Charging time and clock duration may vary depending on the camera.
