Reading Techniques
The imager has a view finder that projects a bright green aiming beam that
corresponds to the imager’s horizontal field of view. The aiming beam should be
centered over the bar code, but it can be positioned in any direction for a good
read.
The aiming beam is smaller when the imager 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 imager at an appropriate distance from the
target, pull the trigger, 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.
