Presentation Mode
Note: Presentation mode does not work when a scanner is programmed for the
laser emulation interface.
Note: If the Presentation Mode selection is enabled, the aimer beam option is
disabled.
The LEDs are off until a bar code is presented to the scanner. Then the LEDs
turn on automatically to read the code. Presentation Mode uses ambient light to
detect the bar codes. 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 imager’s trigger is pulled when using a hands free mode, the
imager changes to manual trigger mode. You can set the time the imager 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 imager
reverts to the original hands free mode.
Scan the Hands Free Time-Out bar code, 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 scanner can read the
same bar code a
second time. Setting a reread delay protects against accidental rereads of the
same bar code. Longer delays are effective in minimizing accidental rereads at
POS (point of sale). Use shorter delays in applications where repetitive bar code
scanning is required.
Default = Medium.
