Note:The image scanner automatically adjusts the illumination LEDs to the low-
est light level possible to maintain a good lock on the Scan Stand symbol.
When a symbol is presented, the image scanner’s light levels adjust to the
saved setting (see LED Power Level on page 4-9). 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 image scanner 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.
Scanning the barcode below programs the image scanner to work in Presenta-
tion 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.
