Olympus C-4040 Zoom - Manual (Page 65)

Focusing
When you place the AF target mark on a subject
and press the shutter button halfway, the green
lamp lights up. This means that focusing is being
performed automatically.
If the green lamp blinks, focusing is not correct. If
this happens, use the AF mode (P. 68), Manual
focus (P. 70) or Focus lock (P. 67).
