Decode Window Function
This is a function that specifies an area for decoding bar code located in the center of the aimer
emitted by the CMOS Imager. It is useful for decoding a specific bar code symbol only among
plural bar codes printed on same paper sheet. If either Mode 1 or Mode 2 of the parameters is
specified in the Decode Window function, the decoding area is automatically determined to
scan only a bar code located near the center. Setting the User Setting effect in the Decode
Window function allows an area of decoding to be specified with X and Y coordinates.

User Setting
If the Decode Window function is set for scanning a bar code, a bar code or a part of the bar
code that is within the aimer's area (see Figure 2.11) is scanned, and other bar codes outside of the
area are not scanned. For example, in Figure 2.11, bar code A cannot be scanned because the
entire bar code is outside of the aimer area, but bar code B can be scanned because a part of the
bar code is within the area.
