Configuració i connectivitat
1. Càrrega de l'escàner
Before initial use, fully charge the scanner using the provided USB charging cable. Connect the small end of the USB cable to the scanner's charging port and the other end to a USB power source (e.g., computer, USB wall adapter). The charging indicator light will show the charging status.
2. Encès / apagat
To power on the scanner, press and hold the trigger button for a few seconds until you hear a beep and see the indicator light. To power off, press and hold the trigger button again until the indicator light turns off.
3. Opcions de connectivitat
The NT-R3 scanner offers two primary connectivity methods:
Bluetooth Connection (HID Mode - Keyboard Emulation)
- Assegureu-vos que l'escàner estigui engegat.
- Scan the "Bluetooth HID Mode" barcode (refer to the Quick Start Guide for specific barcodes).
- Al dispositiu amfitrió (telèfon intel·ligent, tauleta, ordinador), activeu el Bluetooth i cerqueu els dispositius disponibles.
- Select "NETUM Barcode Scanner" or a similar name from the list of devices.
- The scanner will beep to confirm successful pairing.
In HID mode, scanned barcodes are input directly as keyboard entries into any active text field.
Bluetooth Connection (SPP Mode - Serial Port Profile)
SPP mode is typically used for applications that require direct data communication with the scanner. This mode requires specific software on the host device to interpret the data. Refer to your application's documentation for SPP setup.
- Assegureu-vos que l'escàner estigui engegat.
- Scan the "Bluetooth SPP Mode" barcode (refer to the Quick Start Guide).
- Follow the instructions provided by your specific application for connecting to an SPP device.
Connexió sense fil de 2.4 GHz
- Plug the provided 2.4 GHz adapter into a USB port on your computer.
- Assegureu-vos que l'escàner estigui engegat.
- Scan the "2.4G Wireless Mode" barcode (refer to the Quick Start Guide).
- The scanner will automatically connect to the adapter. A successful connection is indicated by a specific beep or light pattern (refer to the Quick Start Guide for details).
The 2.4 GHz connection offers a wireless range of up to 10 meters (30 feet).
Modes de funcionament
The NETUM NT-R3 scanner supports two data upload modes:
1. Instant Upload Mode
In this mode, scanned barcodes are immediately transmitted to your connected device. This is suitable for real-time data entry.
2. Mode d'emmagatzematge
The scanner can store up to 2000 barcodes in its built-in flash memory. This mode is useful when working out of range of your host device. Barcodes can be uploaded later when a connection is established.

Image: A visual representation of the two upload modes. Instant Upload Mode shows barcodes being sent directly to a device. Storage Mode shows barcodes being stored internally and then uploaded later.
To switch between modes, scan the corresponding configuration barcodes found in the Quick Start Guide.
Escaneig de codis de barres
Per escanejar un codi de barres:
- Hold the scanner with the scanning window facing the barcode.
- Press the trigger button. A red scanning line will appear.
- Align the red scanning line across the entire barcode.
- Once successfully scanned, the scanner will emit a beep, and the indicator light will flash.
The NT-R3 is capable of reading 1D barcodes from various surfaces, including:
- Etiquetes impreses
- LCD screens (computers, smartphones, tablets)
- Poorly printed or damaged barcodes
Manteniment
Cura de la bateria
- Per allargar la durada de la bateria, eviteu descarregar-la completament amb freqüència.
