Presentation Mode
Scanning the bar code below programs the image scanner to work in
Presentation Mode. Presentation Mode uses ambient light to detect bar codes.
The LEDs are off until a bar code is presented to the image scanner, then the
LEDs turn on automatically to read the code. If the light level in the room is not
high enough, Presentation Mode may not work properly.
Note: The operation of advanced illumination units and non-advanced
illumination units differs slightly. When an advanced illumination unit is in
Presentation Mode and idle, the illumination LEDs go dim, but never go
out. When a non-advanced illumination unit is in Presentation Mode and
idle, the illumination LEDs go out completely.
Presentation LED Behavior after Decode
When an image scanner is in presentation mode, the LEDs remain on and
continue scanning for a short time after a bar code is decoded. If you wish to
turn the LEDs off immediately after a bar code is decoded, scan the LEDs Off
bar code, below.
Default = LEDs On.
