Illumination
The FM510 has two red LEDs for supplementary lighting, making it possible to scan barcodes even in complete darkness.
The illumination can be programmed On or Off. Customers can add the external illumination system if needed. The spectral
range should be within the visible light.
The illumination LEDs produce a bar-shaped pattern to help the user to easily position the target barcode within the scanner's
field of view to increase scan efficiency.
Note: when the scanner comes closer to the barcodes, illumination center and imaging center may deviate.
