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. page 70

ON, and reading is not correctly performed, then the reading will
be attempted again with a higher or lower gray edge value. (De-

The right/left reversal of the code will be determined
automatically. Use this setting if the codes are not ori-
ented consistently. Processing will be faster if ON or
OFF is used.
