SCANNER OPERATION  
Configurable Primary and Secondary Scan Pattern Modes
There are two configurable scan pattern modes available with the MS3580. 
• The primary scan pattern mode is the default scan pattern active when the 
scanner starts.   
• The secondary scan pattern mode is activated by pressing the button 
located on the side of the scanner.  This mode is also referred to as the 
button mode.  For additional information on Quantum’s button modes and an 
example of each, please refer to Configurable Button Functions below. 
The scanner returns to the primary scan pattern mode after a double 
click of the button or if the unit has not scanned a bar code for the 
duration of a pre-configured time limit. 
Each pattern mode can be configured to use one of three scan patterns listed 
below.  Please refer to the MetroSelect Configuration Guide for information on 
changing the default scan pattern settings. 
•  all scan lines on (omnidirectional reading) 
•  single-line (menu reading) 
•  horizontal raster  
If CodeGate is enabled, it will apply to the secondary pattern mode 
when scanning.  For detailed information on CodeGate and the button 
refer to the Configurable Button Functions. 
Configurable Button Functions
The button on the side of the MS3580 can be configured to function in one of  
four modes.

The following pages include examples of how the button will function when the
