confirm the following items.
1. Shoot the all black subject (Attach
the lens cap and shoot), and con-
firm that a vertical line is not dis-
played in the center of the screen,
and that there is no difference in
left-right brightness level of the
screen.
2. Shoot a subject of low light, and
confirm that a vertical line is not
displayed in the center of the
screen, and that there is no differ-
ence in left-right brightness level
of the screen.
3. Shoot a subject of normal light, and
confirm that a vertical line is not
displayed in the center of the
screen, and that there is no differ-
ence in left-right brightness level
of the screen.
When the above symptom occurs,
perform the whole process of
"Differencal Gain Adjustment".
