5. Operating the Scanner

5.1 Scanning Barcodes

To scan a barcode, point the scanner's window at the barcode and press the trigger button. Ensure the barcode is within the scanner's field of view and properly illuminated.

• The scanner can read 1D barcodes (e.g., UPC, EAN) and 2D barcodes (e.g., QR Code, Data Matrix, PDF417).
• It can scan barcodes from both printed labels and digital screens.

5.2 Scanning Modes

The C750 supports different scanning modes to suit various applications:

• Manual Scan: Press the trigger button for each scan. (Default mode)
• Auto-sensing Scan: The scanner automatically detects a barcode in its field of view and scans it without needing to press the trigger.
• Continuous Scan: The scanner continuously scans barcodes as they pass through its field of view.

Refer to the full user manual or quick start guide for specific configuration barcodes to switch between these modes.

5.3 Data Upload Modes

The scanner offers two ways to handle scanned data:

• Instant Upload Mode: Barcodes are transmitted to the connected device immediately after scanning. This is the default mode.
• Storage Mode (Offline Mode): Scanned barcodes are stored in the scanner's internal memory. This is useful when out of range of the connected device. The scanner can store up to 100,000 barcodes. To upload stored data, scan the "Upload Data" barcode (refer to the full manual).

5.4 Transmission Range

The effective transmission range varies depending on the connection mode and environment:

• Bluetooth Mode: Approximately 10m (32 ft) with obstacles, 20m (65 ft) in barrier-free environments.
• 2.4G Wireless Mode: Approximately 15m (49 ft) with obstacles, 50m (164 ft) in barrier-free environments.
