Battery Charge Level
The level of charge remaining in the batteries is shown by the battery
icon on the display. This icon gives you a rough idea of how much of
a charge is left in the batteries.
– When the icon appears completely filled, the batteries are fully charged.
– When the icon appears partially filled, the battery charge is getting low.
– When the icon appears empty, the batteries must be replaced.
NOTE: Pictures remain stored even if the batteries are empty.
