<Notes>
≥
Check that the lens connector has been connected and
that the lens aperture is set to CLOSE.
≥ While the black balance is being adjusted, the aperture
is automatically set to the light-shielding status.
≥ While the black balance is being adjusted, the gain
selector circuit is switched automatically.
Flicker or noise may appear on the viewfinder screen,
but this is not indicative of malfunctioning.
≥ If the black shading is still unsatisfactory although the
“ABB OK” message is displayed, perform menu
operations to open the <BLACK SHADING> screen
from the MAINTENANCE page, move the arrow mark
(
>) to the DETECTION item, press the JOG dial
button, and proceed with the black shading adjustment.
If the ABB switch is held down for 5 or more seconds,
the black shading can be automatically adjusted after
the ABB operation. (See the SHD.ABB SW CTL item
under “7-5-5 SW MODE.”)
≥ If the AUTO W/B BAL switch is pushed down to the
ABB position again while the black balance is being
automatically adjusted (ABB ACTIVE), the adjustment
will be aborted.
The adjusted value in this case is the value before
automatic adjustment was performed.
Black balance memory
The values stored in the memory are retained even after the
