3 - 14 4600g, 4600r, 4800i User’s GuideDecode Search ModeThere are three selectable decode (scanning) modes:Full Omnidirectional - Searches for bar code features beginning at the centerof an image, and searches to the image’s limits. This mode reads allsymbologies (including OCR), in any orientation. The Full Omnidirectionalsearch is very thorough which may slow performance time.Note: This search mode is the default setting.Quick Omnidirectional - This is an abbreviated search for bar code featuresaround the center region of an image. This mode quickly reads all symbologiesin any orientation. The Quick Omnidirectional mode may miss some off-centersymbols, as well as larger Data Matrix and QR Code symbols.Advanced Linear Decoding - Performs quick horizontal linear scans in a centerband of the image. This mode isnot omnidirectional, but does quickly read linearand stacked bar codes. Advanced Linear Decoding cannot read 2D, OCR, orPostal symbols.Preferred SymbologyNote: This selection applies to the 4600r only. It does not apply to OCR.The 4600r can be programmed to specify one symbology as a higher priority overother symbologies in situations where both bar code symbologies appear on thesame label, but the lower priority symbology cannot be disabled.For example, you may be using the imager in a retail setting to read UPCsymbols, but have occasional need to read a code on a drivers license. Sincesome licenses have a Code 39 symbol as well as the PDF417 symbol, you canuse Preferred Symbology to specify that the PDF417 symbol be read instead ofthe Code 39.Full OmnidirectionalQuick OmnidirectionalAdvanced Linear Decoding
