At a distance of 20 cm - 30 cm (0.7 ft.
- 1.0 ft.), fill the viewfinder with a
patternless, solid-white object and
take a picture.
The picture will be taken in aperture-
priority AE mode at an aperture of
f/22.
Since the image will not be saved, the
data can still be obtained even if there
is no card in the camera.
When the picture is taken, the camera
will start collecting the Dust Delete
Data. When the Dust Delete Data is
obtained, a message will appear.
If the data is not obtained
successfully, an error message will
appear. Follow the "Preparation"
procedure on the preceding page,
then select [OK]. Take the picture
again.
