3.2.1 2.4G Wireless Connection (Default)
The scanner is pre-configured for 2.4G wireless mode. Simply plug the 2.4G USB receiver (dongle) into your computer's USB port. The scanner will automatically connect. No software or drivers are required for this mode (Plug and Play).
To re-pair the 2.4G wireless connection, scan the "Receiver mode(*)" barcode from the instruction manual, then plug in the USB receiver. The indicator light will flash green, then turn solid green upon successful pairing.
3.2.2 Bluetooth Connection
To use Bluetooth mode:
- Scan the "Bluetooth HID mode" barcode from the instruction manual. The scanner's indicator light will flash blue and green, indicating it's waiting for pairing.
- On your device (phone, tablet, or computer), open Bluetooth settings and search for "Barcode Scanner HID".
- Select "Barcode Scanner HID" to connect. The scanner will beep, and the indicator light will stop flashing, turning solid blue or green to confirm successful pairing.
- To pair with a different device, scan the "Pair setting" barcode from the instruction manual to enter pairing mode again.
3.2.3 USB Wired Connection
Connect the scanner directly to your computer using the provided USB cable. The scanner will function as a wired scanner and will also charge simultaneously. No additional setup is required.
4. Operating Modes
The scanner offers various scanning modes to suit different operational needs.
4.1 Trigger Modes
- Manual Scan Mode: Press the trigger button to scan each barcode.
- Auto Sensing Mode: The scanner automatically detects and scans barcodes when they are presented within its scanning range, without needing to press the trigger.

- Uploading Data: To upload stored data to your connected device, scan the "Upload data" barcode from the instruction manual.
- Deleting Data: To clear all stored barcode information from the scanner, scan the "Delete all data" barcode from the instruction manual. This prevents exceeding storage capacity.
- Exiting Inventory Mode: To return to normal scanning operation, scan the "Immediate Mode" barcode from the instruction manual.
