4. Operating Instructions
4.1 Basic Scanning
To scan a barcode, aim the laser beam at the center of the barcode and press the trigger button. A successful scan is usually indicated by a beep and/or a green LED light.
4.2 Data Upload Modes
The scanner supports two modes for uploading scanned data:
4.2.1 Instant Upload Mode
In this mode, scanned barcodes are immediately transmitted to the connected computer. This is suitable for real-time data entry.
4.2.2 Storage Mode
When the scanner is out of range of the receiver or disconnected, it can store scanned barcodes internally. The scanner supports storing approximately 1000 barcodes in offline memory. To upload stored data, reconnect the scanner to your computer (either wirelessly or via USB) and scan the specific 'Upload Data' barcode (refer to the programming guide for this barcode, if provided). The stored data will then be transmitted to your computer.
