Selecting the Interface Type
Quick Reference Guide 7
A beam illuminates the label. The projected pattern of the aiming sys-
tem 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 ele-
ments (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 good-read green spot LED
indicator.
Relative Size and Location of Green Spot
