Maintenance
* The window must be kept clean; the supplier does not bear the guarantee responsibility
due to the improper maintenance.
* Avoid the window being wear and tear or scratched by hard object
* Use the hairbrush to remove the stain on the window
* Clean the window with a soft cloth, such as lens cleaning cloth
* Spraying liquid onto the window is prohibited.
* Prohibit any cleaning solvents, except for the cleaning water.
Reading skills
If the barcode is small, it should be closer to the scanning window; if the barcode is large,
it should be far away from the scanning window a little more, thus easier to be read correctly.
If the barcode is highly reflective (for example, the coated surface), you may need to tilt
the barcode at an angle to successfully scan it.
