The LEDs in the center of both keyboards (for location, see LEDs on page 4-1 ) light when using the image engine.
Scan LED The LED on the right lights red when you press the scan trigger in scanning applications.
Decode LED The LED on the left lights green when a scanned bar code is successfully decoded.
Decoding
The Dolphin terminal supports two types of image decoding: full-area imaging and Advanced Linear Decoding (ALD).
Full-area Imaging
Full-area imaging means that the Dolphin terminal support omni-directional aiming, which means that a positive
read can be obtained from many positions. For details, see
Omni-Directional Scanning Positions on page 5-4.
ALD
ALD provides fast reading of linear (1D) and stacked linear bar codes (e.g., PDF417). For the best read, the aiming
pattern should be centered horizontally across the bar code. When ALD is enabled, the reader does not read matrix
or postal codes.
