Setup
12 Heron™ HD3430
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 good-read green spot LED indicator.
