Omni-Directional Scanning
Dolphin terminals support omni-directional scanning.
In general, the aiming pattern or beam is smaller when the terminal is held closer to the bar code and
larger when farther from the bar code. Symbologies with smaller bars or elements (mil size) should be
read closer to the terminal whereas larger bars or elements (mil size) should be read farther from the
terminal.
Note: To achieve the best read, the aiming beam should be centered horizontally across the bar code.
5300 High-Vis Aiming Pattern
The red high-vis aiming pattern frames the bar code.
5100 Green Aiming Beam
The green aiming beam projects outward in a straight line across the bar code.
Laser Engines (HP, LR, and ALR)
Laser engines do not support omni-directional scanning.
To achieve a successful scan, the red beam must completely cover the bar code as in the following
example:
To avoid specular reflection when scanning (i.e., the glare), do not aim the laser so that the beam is
reflected straight back. Instead, aim the laser so that it's slightly off-center of the target bar code.
