Replacing the Button Battery
If the Set Date/Time menu appears when you turn on the camera power, the button
battery charge is low and the date and time settings have been lost. Please replace the
battery with a generic CR2016 lithium button battery with the following procedures.
The button battery is preinstalled at the factory and may therefore expire earlier
than its rated lifespan after the camera has been purchased.
• Be particularly careful to keep the button batteries out of the reach of children.
Seek medical assistance immediately if a child swallows a battery since corrosive
battery fluids could damage the stomach or intestinal wall.
