For the reading distance measuring reference, see page 74.
Note 1: The readable label width means a bar code length including the right and
left margins (quiet zones) of a bar code.
Note: 2 Even if a bar code is within the above reading range, it may not be read
depending on the bar code quality. Set the optimum reading position based on
enough reading tests.
Note 3: It is recommended that the focal length (90 mm) is set as the mounting
distance. In this case, the maximum readable label width is 86 mm.
