Presentation Mode
Presentation Mode uses ambient light and scanner illumination to detect bar 
codes.  When in Presentation Mode, the LEDs remain dim until a bar code is pre-
sented to the scanner, then the aimer turns on and the LEDs turn up to read the 
code.  If the light level in the room is not high enough, Presentation Mode may not 
work properly   
Scan the following bar code to program your scanner for Presentation Mode.
LED Illumination - Presentation Mode
If you wish to set the illumination LED brightness, scan one of the bar codes 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: 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 bar codes. 
Note: LED Illumination - Presentation Mode does not apply to Streaming Presentation™ 
Mode or Mobile Phone Read Mode.
