Selecting the Interface
Type
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 S2 Product Reference Guide (PRG) on the
AirTrack website for more information about this feature
and other programmable settings.
