When a scanning application is open, press the SCAN key 

 to activate the image engine. You can 

in a scanning application by default.

Demos are software utilities loaded on all Dolphin terminals that demonstrate the advanced features of 
the terminal. There are two Demos feature the image engine: Image Demo and Scan Demo.

To access these demos, tap Start > Demos,

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

) 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.

The Dolphin terminal supports two types of image decoding: full-area imaging and Advanced Linear 
Decoding (ALD).

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 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.

1.

Tap Start > Demos > Scan Demo.

2.

Position the Dolphin terminal over one of the sample bar codes on page 

.

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; 

5.

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