AThe Built-in Flash

If additional lighting is required for correct exposure in i mode, the built-in flash will pop up automatically when the shutter-release button is pressed halfway. If the flash is raised, photographs can only be taken when the flash-ready indicator (M) is displayed. If the flash- ready indicator is not displayed, the flash is charging; remove your finger briefly from the shutter-release button and try again.

To save battery power when the flash is not in use, return it to its closed position by pressing it gently downward till the latch clicks into place.
