Using the Gryphon™ I GBT/GM4500
Quick Reference Guide 17
Linear Bar
A red beam illuminates the label. The field of view indi-
cated by 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 far-
ther 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. Successful 
reading is signaled by an audible tone plus a good-read 
green spot LED indicator.
Refer to the Gryphon I GBT/GM4500 Product Reference 
Guide (PRG) for more information about this feature and 
other programmable settings.
