Streaming Presentation Mode
When in Streaming Presentation Mode, the scanner’s illumination remains on all 
the time to continuously search for barcodes. Two modes are available: Normal and 
Enhanced. Normal mode offers good scan speed and the longest working range 
(depth of field). Enhanced mode will give you the highest possible scan speed but 
slightly less range than Normal mode. Enhanced mode is best used when you 
require a very fast scan speed and don’t require a long working range. Default 
Streaming Presentation Mode = Normal.
Read Mode
Read mode allows you to prioritize barcode by the type of media. When in Paper 
and Screen mode, the scanner will give you a balanced scan speed on printed 
barcodes, mobile phone screens or other digital barcodes. Paper-Only gives the 
highest possible scan speed on printed barcodes but slightly less scan speed on
