Presentation LED Behavior after Decode
When a scanner is in presentation mode, the LEDs dim 30 seconds after a bar code
is decoded. If you wish to dim the LEDs immediately after a bar code is decoded,
scan the LEDs Off bar code, below. Default = LEDs On.
Presentation Sensitivity
Presentation Sensitivity is a numeric range that increases or decreases the scan-
ner's reaction time to bar code presentation. To set the sensitivity, scan the Sensi-
tivity bar code, 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.
Presentation Centering
Use Presentation Centering to narrow the scanner’s field of view when it is in Pre-
sentation Mode to make sure the scanner reads only those bar codes intended by
the user. For instance, if multiple codes are placed closely together, Presentation
Centering will insure that only the desired codes are read.
Note: To adjust centering when the scanner is hand-held, see Centering (page 3-49).
If a bar code is not touched by a predefined window, it will not be decoded or output
by the scanner. If Presentation Centering is turned on by scanning Presentation
Centering On, the scanner only reads codes that pass through the centering win-
dow you specify using the Top of Presentation Centering Window, Bottom of Pre-
sentation Centering Window, Left, and Right of Presentation Centering Window bar
codes.
