If the maximum aperture (f/2.8, etc.) appears, it
should be reset by moving the same toward the
direction of the minimum aperture If/22, etc.).
The process should be reversed in the similar
manner, when the displayed value is the minimum
aperture (f/22, etc.) by changing the aperture
in the direction of maximum aperture.
Should the situation return to normal, that is,
within the shutter/aperture coupling range by
changing the f/stop, the flow-like flickering will
cease and proper exposure is indicated and
photographs may be taken in this AE mode.
Whenever the situation exceeds the meter coupling
range for proper exposure, the following shutter
speed/aperture value indications will appear:
