Presentation Mode
Note: The operation of light bar off-axis illumination units and non-light bar units
differs slightly. When a light bar unit is in Presentation Mode and idle, the
illumination LEDs go dim, but never go out. When a non-light bar unit is in
Presentation Mode and idle, the illumination LEDs will go out completely.
Scanning the barcode below programs the image scanner to work in
Presentation Mode. Presentation Mode uses ambient light to detect barcodes.
The LEDs are off until a barcode 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.
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 barcode is decoded. If you wish to turn
the LEDs off immediately after a barcode is decoded, scan the
LEDs Off
barcode, below.
Default = LEDs On.
Presentation Sensitivity
Presentation Sensitivity is a numeric range that increases or decreases the
image scanner's reaction time to barcode presentation. To set the sensitivity,
scan the
Sensitivity
barcode, then scan the degree of sensitivity (from 0-20)
from the inside back cover, and
Save
. 0 is the most sensitive setting, and 20 is
the least sensitive.
Default = 1.
