Olympus 170 - Manual (Page 35)

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.
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 2 seconds) is
automatically selected in low-
light situations, the use of a
tripod is recommended. Closing
the lens barrier restores the Auto
Flash mode.
