Olympus Stylus Zoom 115 - Manual (Page 37)

OFF (Flash Override)
When you don't want the flash to fire even in
the dark or when you want to shoot such
subjects as fireworks.
In the Flash-Off mode, the flash does not fire even in
low-light conditions. Use this mode in situations where
flash photography is not desired or is prohibited or in
twilight or night scenes.
Note: Since a slow shutter speed (down to 4 seconds) is
automatically selected in low-light situations when in the
Flash-Off mode, the use of a tripod is recommended to
prevent blurred pictures caused by shaking the camera.
Closing the lens barrier returns to Auto.
