Reading Techniques
The hand-held Imager has a view finder (shown below) which is similar to those
on cameras. The view finder allows you to position the code within the field of
view.
The illustration below shows where to aim the red illuminated beam over the
symbol for a good read. Center the symbology in the view finder. The entire
symbology must be within the view finder (aiming beam). The view finder
changes size as you move the Imager closer to or farther away from a code.
Note: The symbols can be in any orientation for the Imager to read.
The view finder 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. (see "Depth of Field Charts "on page
1-8.) 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
view finder cross hairs on the symbol.
