Adjust power management settings.
Choose the length of time before the camera turns off automatically when no operations are performed. Shorter times reduce the drain on the battery; if [OFF] is selected, the camera must be turned off manually. Note that in some situations the camera turns off automatically even when [OFF] is selected.
Select [ON] to reduce power consumption and increase the number of pictures that can be taken on a single charge when pictures are framed in the optical viewfinder.
Power consumption is not reduced when the electronic viewfinder or electronic range finder is used.
Select [ON] for faster focus and to reduce the time needed to restart the camera after it has been turned off.
