1. Dirt and dust on the scanning window sometimes affect the normal operation of the
barcode scanning device. When cleaning, you should use a good quality facial tissue to
gently wipe, or use a soft cloth to clean. If the paper with poor paper quality is used for
wiping for a long time, it will damage the surface finish of the window and affect the
reading effect of the barcode scanning device.
2. The outer shell of the barcode scanning device can be wiped with a clean soft cloth.
If necessary, a small amount of detergent can be added to the water and wiped with a
soft cloth dipped in water.
3. Do not spray any liquid on the window.
4. The scanning window must be kept clean, and the supplier is exempt from warranty
for damage caused by improper maintenance.
