Product Reference Guide 27
A red beam illuminates the label. The field of view indicated by 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 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 and 
the entire bar code is within the aiming field, you will get a good read. Success-
ful reading is signaled by an audible to
ne plus a good-read green spot LED 
indicator.
