Omni-Directional Scanning Positions
The high-vis aiming pattern frames the bar code to provide you with the best scanning performance.
Note: To achieve the best read, the aiming beam should be centered horizontally across the bar code.
The aiming pattern is smaller when the terminal is held closer to the code and larger when the terminal is
held farther from the code. Symbologies with smaller bars or elements (mil size) should be read closer to
the unit whereas larger bars or elements (mil size) should be read farther from the unit.
