Presentation Mode
The LEDs are off until a barcode is presented to the image scanner. Then the
LEDs turn on automatically to read the code. Presentation Mode uses ambient
light to detect the barcodes. If the light level in the room is not high enough,
Presentation Mode will not work properly.
Hands Free Time-Out
The Automatic Trigger and Presentation Modes are referred to as “hands free”
modes. If the image scanner’s trigger is pulled when using a hands free mode,
the image scanner changes to manual trigger mode. You can set the time the
image scanner should remain in manual trigger mode by setting the Hands Free
Time-Out. Once the time-out value is reached, (if there have been no further
trigger pulls) the image scanner reverts to the original hands free mode.
Scan the Hands Free Time-Out barcode, then scan the time-out duration (from
0-300,000 milliseconds) from the inside back cover, and Save . Default = 5,000
ms.
Reread Delay
This sets the time period before the image scanner can read the same barcode
a second time. Setting a reread delay protects against accidental rereads of the
same barcode. Longer delays are effective in minimizing accidental rereads at
POS (point of sale). Use shorter delays in applications where repetitive barcode
scanning is required.
Default = Medium.
