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 (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.
To Decode a Bar Code

Tap Start > Demos > Scan Demo.
2.
Position the Dolphin terminal over one of the sample bar codes on page
5-4

A range of 4–10 inches (10–25 cm) from the bar code is recommended.
3.
Project the aiming brackets by pressing and holding the SCAN key. The Scan LED lights red
.
4.
Center the aimer crosshair over the bar code. The aiming beam should be oriented in line with the
bar code to achieve optimal decoding;
