3. Operating Instructions

The D7800 scanner operates in an automatic, hands-free mode. Simply place the item with the barcode in front of the scanner's window.

• Automatic Sensing: The scanner features an auto-sensing function. When a barcode is presented within its scanning field, the scanner will automatically activate its light and attempt to read the barcode.
• Scanning Technique: Position the barcode so it is fully visible to the scanner's window. A successful scan is typically indicated by an audible beep and the barcode data appearing on your connected device.
• Scanning from Screens: The CCD scanning technology allows for efficient reading of barcodes displayed on mobile phone screens, tablets, and computer monitors. Ensure the screen brightness is adequate for optimal scanning.

• Storage: Store the scanner in a clean, dry environment away from extreme temperatures and direct sunlight when not in use.
• Cable Care: Avoid bending or twisting the USB cable excessively to prevent internal damage.
