The reading conditions can be set manually. If parameters have been
set using the teaching function, those parameters can be viewed or
changed, if necessary, from this menu.

1. Select the color of symbol.
2. Select whether Right & Left Reverse of QR Codes is necessary.
3. Select the gray edge value (i.e., the ratio of black and white) used
to detect finder patterns. (Setting range: 1 to 127; default setting:
32.)
If the ratio of the intensity of black and white is large, set to a large
value, and if the ratio of the intensity of black and white is small,
set it to a small value.
This setting can be made using the teaching function (which au-
tomatically measures the optimum value), so whenever resetting
the reading conditions, always use this function first.
