Using the Wasp WDI4200
A beam illuminates the label. The projected pattern of the
aiming system will be smaller when the reader is closer to
the bar code and larger when it is farther from the code.
Symbologies with smaller bars or elements (mil size)
should be read closer to the unit. Symbologies with larger
bars or elements (mil size) should be read farther from the
unit. If the aiming system is centered you will get a good
read. Successful reading is signaled by an audible tone plus
a goodread green spot LED indicator. Reference the Wasp
WDI4200 Product Reference Guide (PRG) on the Wasp
website for more information about this feature and other
programmable settings.
