3. Operating Instructions
Basic Scanning Operation:
To scan a barcode, aim the scanner's light at the barcode and press the trigger button. The scanner will emit a beep and the display screen will show the scanned data.
Display Screen Functionality:
The 1.9-inch TFT color LCD screen provides real-time feedback on your scanning activities and scanner status.

Storage vs. Normal Mode:
A toggle switch allows you to select between two operational modes:
- Storage Mode: When set to 'Storage', the scanner saves scanned barcodes internally. This is useful when working away from a computer. Data can be uploaded later. The scanner can store up to 10,000 codes.
- Normal Mode: When set to 'Normal', scanned barcodes are transmitted directly to the connected computer or device in real-time.
