5. Operation
5.1. Scanning Modes
The scanner offers three distinct scanning modes, configurable via the setting keypad or by scanning specific barcodes (refer to the quick start guide for setup barcodes if preferred over keypad menu):
- Manual Trigger Mode: Press the scan button to activate the scanner and read a barcode.
- Auto-sensing Scan Mode: The scanner automatically detects a barcode within its field of view and scans it without requiring a button press.
- Continuous Scan Mode: The scanner continuously emits a scan beam, reading any barcode that passes through it.
Image: Three scenarios demonstrating the scanning modes: a hand holding the scanner to scan a barcode on a phone (Manual Trigger Mode), a worker scanning a barcode on a box (Auto-sensing Scan Mode), and the scanner positioned over a conveyor belt scanning packages (Continuous Scan Mode).
5.2. Data Uploading Modes
Choose between instant upload or inventory storage for your scanned data:
- Instant Upload Mode: Barcodes are immediately transmitted to the connected device (computer, POS, smartphone) as they are scanned.
- Inventory Mode (Storage Mode): Barcodes are stored internally in the scanner's memory. The scanner can store over 50,000 barcodes. Data can be uploaded to the connected device at a later time.
