Selecting the Interface Type
4 QuickScan™ QD2430
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. Symbolo-
gies 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. Suc-
cessful reading is signaled by an audible tone plus a good-
read green spot LED indicator.
Reference the QuickScan QD24XX Product Reference Guide
(PRG) on the Datalogic website for more information about
this feature and other programmable settings.
