Replacing the Date Time Battery

The date/time (back-up) battery maintains the camera's date and time. Its service life is about 5 years. If the date/time is reset when the battery is replaced, replace the back-up battery with a new CR2016 lithium battery as described below.

The date/time setting will also be reset, so be sure to set the correct date/time.
