Reading Techniques
The Imager has a viewfinder 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.
Figure 1-2. Aiming Beam Positioning
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.
