Guide–Preliminary
To Decode a Bar Code
1. 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 pattern by pressing and holding the Scan trigger. The Scan LED lights red
.
4. Center the aiming beam over the bar code. The aiming beam should be oriented in line with the bar code to achieve optimal
decoding; see Omni-Directional Scanning Positions on page 5-4.
5. Release the Scan trigger.
6. When the bar code is successfully decoded, the decode LED lights green and the terminal beeps.
Sample Bar Codes
You can use the following bar codes to verify decoding:
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.
Laser Engines
Laser engines do not support omni-directional scanning. To achieve an optimal scan, center the red aiming beam across the bar
code horizontally as shown.
