Using the scanner

The scanner normally functions by capturing and decoding codes. The aiming system is activated on trigger

pull and indicates the center of the field of view which should be positioned over the bar code:

Figure 4-13 Aiming System

Figure 4-14 Linear bar code

Figure 4-15 2D Matrix symbol

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.

Refer to the Programming Reference Guide (PRG) for more information about this feature and other

programmable settings.
