LED Illumination - Presentation Mode
If you wish to set the LED illumination brightness, scan one of the barcodes below. 
This sets the LED illumination for the scanner when it is in Presentation Mode. If 
the scanner is triggered manually, the LED illumination will switch to the setting 
for a manual trigger. (See LED Illumination - Manual Trigger on page 38.)  
Default = High.
Note: This command is not supported by the Gen 7 software revision. For scanners with the 
Gen 7 revision, use LED Illumination - Manual Trigger on page 38 for both 
Presentation Mode and Manual Mode. For infomation about software revisions, see 
About Software Revisions on page 6.
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: LED Illumination - Presentation Mode does not apply to Streaming Presentation™ 
Mode or Mobile Phone Read Mode.
Presentation LED Behavior after Decode
When a scanner is in presentation mode, the LEDs dim 30 seconds after a barcode 
is decoded. If you wish to dim the LEDs immediately after a barcode is decoded, 
scan the LEDs Off barcode, below. Default = LEDs On.
