Decoding

The Dolphin terminal supports two types of image decoding for use in various bar code reading and imaging applications: full-
area imaging and Advanced Linear Decoding (ALD).
Full-area Imaging
Full-area imaging provides omni-directional reading of linear and non-linear 1D and 2D bar codes, OCR, signature capture, and
picture taking. When reading all bar code types using full-area imaging, a positive read can be obtained from many positions;
see Omni-Directional Scanning
the bar code.
ALD
ALD provides fast reading of linear and stacked linear bar codes. To achieve a positive read when reading linear 1D and PDF417
bar codes, the green aiming beam 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
1. Tap Start > Demos > Scan Demo.
2. Position the Dolphin 7900 terminal over the bar code. A range of 4-10 inches (10-25 cm) from the bar code is
recommended.
3. Project the aiming pattern by pressing and holding the SCAN key or one of the side buttons;
(see page 5-3). The Scan LED lights
4. Center the aiming pattern over the bar code. For optimal decoding, make sure the aiming beam is in line with the bar code.
5. Release the SCAN key or side button.
6. When the bar code is successfully decoded, the decode LED lights and the terminal beeps;
