Illumination
The EM2037 has two red LEDs (wavelength: 612nm-624nm) for supplementary lighting, making it possible to scan barcodes
even in complete darkness. The illumination can be turned On or Off. The EM2037 uses red LEDs for illumination, so the
engine shows better reading performance on barcodes printed in non-red colors. For applications involving red barcodes, it
is advised to turn off the
engine’s illumination and use non-red supplementary lighting (such as green) instead. The user can
conduct some tests to determine the proper wavelengths to be used.
Aimer
The EM2037 has a view finder that projects a bar-shaped aiming pattern to help the user to position the target barcode within
the engine
’s field of view to increase scan efficiency. The aimer can be programmed On or Off. It is advisable to turn it on
when scanning barcodes.
