Bluetooth Connection (HID Mode - Keyboard Emulation)
- Ziurtatu eskanerra piztuta dagoela.
- Scan the "Bluetooth HID Mode" barcode (refer to the Quick Start Guide for specific barcodes).
- On your host device (smartphone, tablet, computer), enable Bluetooth and search for available devices.
- 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.
- Ziurtatu eskanerra piztuta dagoela.
- 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.
2.4 GHz Haririk gabeko konexioa
- Plug the provided 2.4 GHz adapter into a USB port on your computer.
- Ziurtatu eskanerra piztuta dagoela.
- 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).
Funtzionamendu moduak
The NETUM NT-R3 scanner supports two data upload modes:
1. Berehalako kargatze modua
In this mode, scanned barcodes are immediately transmitted to your connected device. This is suitable for real-time data entry.
2. Biltegiratze modua
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.

Barra-kode bat eskaneatzeko:
- Eutsi eskanerrari eskaneatze-leihoa barra-kodeari begira duela.
- 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:
- Inprimatutako etiketak
- LCD screens (computers, smartphones, tablets)
- Poorly printed or damaged barcodes
Mantentzea
Bateria zaintzea
