Hand Held Products 7900 Series 用户手册

The Dolphin 7900 offers the following options to activate the engine:

•           The Scan key located in the center the keyboards for easy access from either hand - see 

•           The buttons located on both side panels - see 

 

The buttons on the side panel - 

 on page 3-6 - activate the imager by default. These buttons can be 

programmed to perform specific functions as well as open software applications. To program these buttons, see 

 If the buttons on the side panel have not been programmed, pressing either one will activate the image engine.

All Dolphin 7900 terminals contain demos that enable you to test and verify the image engine. To access these demos, go to 
Start > Demos,

•           Select Image Demo to verify imaging, or
•           Select Scan Demo to verify decoding.

The Dolphin 7900 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 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 

 To achieve the best read, the aiming beam should be centered horizontally 

across the bar code. 

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.

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 imager’s aiming beam by pressing and holding the SCAN key or side button; 

5-3‘.

4. The Scan LED lights red; 

5. Center the aiming beam over the bar code. The aiming beam should be oriented in line with the bar code to achieve optimal 

6. Release the SCAN key or side button.

7. When the bar code is successfully decoded, the decode LED lights green and the terminal beeps;
