Operating Instructions
Scanning Barcodes
- Handheld Mode: Hold the scanner with the scanning window facing the barcode. Press and hold the yellow trigger button to activate the laser. Aim the laser beam across the entire barcode. A successful scan will be indicated by a beep and/or a green light.
- Autosense Mode (Hands-Free): When placed on its stand, the SC100 can operate in autosense mode. The scanner will automatically detect a barcode placed within its scanning field and activate the laser to read it without requiring the trigger button to be pressed.
Integration with POS Systems
The 3nStar SC100 functions as a keyboard wedge device, meaning it inputs scanned data directly as if it were typed on a keyboard. This allows for seamless integration with various Point of Sale (POS) software and applications, including:
- pcAmerica
- Aldelo
- Quickbooks
- And other applications that accept keyboard input for barcode data.
Simply place your cursor in the desired input field within your software, and scan the barcode. The data will appear automatically.
Maintenance
- Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild, non-abrasive cleaner to wipe the scanner's exterior, especially the scanning window. Do not use harsh chemicals or abrasive materials.
- Handling: While designed to be durable, avoid dropping the scanner from excessive heights or subjecting it to severe impacts. Keep the scanning window clear of scratches and debris.
- Storage: Store the scanner in a clean, dry environment away from extreme temperatures and direct sunlight when not in use.
Troubleshooting
