4 - 6Dolphin® 9500/9550 Mobile Computer User’s GuideImagerThe terminal houses a compact image engine that instantly reads all popular 1D and 2D bar codes and supports omni-directionalaiming and decoding for greater flexibility in real-world settings. The image engine can also capture digital images, such assignatures and pictures of damaged inventory. Images are saved in industry-standard file formats.DecodingThe terminal supports two types of image decoding for use in various bar code reading and imaging applications: full-areaimaging and Advanced Linear Decoding (ALD).Full-area ImagingFull-area imaging provides omni-directional reading of linear and non-linear 1D and 2D bar codes, OCR, signature capture, andpicture taking. When reading all bar code types using full-area imaging, a positive read can be obtained from many positions;see Scanning Position Options on page 4-7. To achieve the best read, the aiming beam should be centered horizontally acrossthe bar code.ALDALD provides fast reading of linear and stacked linear bar codes. To achieve a positive read when reading linear 1D and PDF417bar codes, the green aiming beam should be centered horizontally across the bar code. When ALD is enabled, the reader doesnot read matrix or postal codes.To Decode a Bar Code1. Point the Dolphin 9500/9550 terminal directly at the bar code. The imager faces straight out the top panel.The aiming beam should be oriented in line with the bar code to achieve optimal decoding. A range of 4-10 inches (10-25 cm)from the bar code is recommended.2. Project the imager’s green aiming beam by:• Pressing and holding the SCAN key on both the 9500 and 9550.• Pressing and holding the Scan Trigger on the 9550.3. The scan LED lights red.4. Center the aiming beam over the bar code.5. When the bar code is successfully decoded, the decode LED lights green and the terminal beeps.6. The bar code information is entered into the application in use.DOLPHIN 9500Scan LEDDecode LED
