the cable with the label “DO NOT connect this end to the bar code scanner” plugs into
the computer.
Reading Techniques
The scanner has a view finder that projects a bright green aiming beam that corre-
sponds to the scanner’s horizontal field of view. The aiming beam should be cen-
tered over the bar code, but it can be positioned in any direction for a good read.
The aiming beam is smaller when the scanner is closer to the 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. To read single or multiple symbols (on a
page or on an object), hold the scanner at an appropriate distance from the target,
push the button, and center the aiming beam on the symbol. If the code being
scanned is highly reflective (e.g., laminated), it may be necessary to tilt the code up
15° to 18° to prevent unwanted reflection.
