If you want to set the LED illumination brightness, scan one of the barcodes below. 
This sets the LED illumination for the scanner when the button is pushed. Default = 
High. 
Note: The LEDs are like a flash on a camera. The lower the ambient light in the room, the 
brighter the LEDs need to be so the scanner can “see” the barcodes.
Note: For scanners with the Gen 7 software revision, this setting applies to both Manual 
Mode and Presentation Mode. 
For Manual Mode with Gen 7, you must first scan the Set Exposure Mode - Manual 
Trigger Mode barcode before setting the LED illumination brightness. See LED 
Illumination Exposure Mode - Manual Trigger on page 39.
For Presentation Mode with Gen 7, you must first use the Set Exposure Mode - 
Presentation Mode barcode before setting the LED illumination brightness. See LED 
Illumination Exposure Mode - Presentation Mode on page 39.
