Note: The imager automatically adjusts the illumination LEDs to the lowest light
level possible to maintain a good lock on the Scan Stand symbol. When
a symbol is presented, the imager’s light levels adjust to the saved setting
(see LED Power Level on page 3-9). This mode requires at least 50 lux
of ambient light to operate correctly.
Scan Stand Symbol
When a unit is in Scan Stand mode, the LEDs shine at the Scan Stand symbol
on the base of the stand which tells it to remain idle.
When the Scan Stand
symbol is covered, the imager turns the LEDs on at the configured power level
(Default High) and attempts to find and decode barcodes in its field of view.
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.
This programs the imager to work in Presentation mode. The LEDs are either off
or at the lowest power for ambient conditions until a barcode is presented to the
imager. 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 may not work properly.
