Product Overview
The NETUM NT-M2 is a portable laser barcode scanner designed for efficient 1D barcode reading. It offers both wireless (433MHz) and wired (USB) connectivity options, making it versatile for various applications. It features 256KB flash memory, capable of storing up to 3000 barcodes.

This image illustrates the ergonomic design of the scanner and its use in scanning barcodes from documents and packages.
Setup
1. Wireless Setup (433MHz)
- Insert the 433MHz USB wireless receiver into an available USB port on your computer (PC or Laptop).
- The operating system will automatically detect and install the necessary drivers. No manual driver installation is required.
- Turn on the barcode scanner. It should automatically pair with the receiver. A successful connection is usually indicated by a specific sound or LED indicator on the scanner.
- Open a text editor, spreadsheet, or any application where you want the scanned data to appear.
- Scan a test barcode to confirm the connection and data transmission.

- Windows XP
- Windows 7
- Windows 8
- Windows 10
- Linux
- Mac OS

This image visually confirms compatibility with various Windows versions, Linux, and Mac operating systems.
Operating Instructions
1. Basic Scanning
- Ensure the scanner is powered on and connected to your computer (either wirelessly via the receiver or directly via USB).
- Point the scanner's laser beam at the barcode you wish to scan.
- Press and hold the trigger button. A red laser line will appear.
- Align the laser line across the entire barcode.
- Upon successful scan, the scanner will emit a beep, and the data will appear in your active application on the computer.

2. Data Storage Mode (Offline Mode)
The NT-M2 features 256KB of flash memory, allowing it to store up to 3000 barcodes when out of range or disconnected from the receiver. To use this feature:
- Scan barcodes as usual. The scanner will store them internally if no connection is detected.
- To upload stored data, reconnect the scanner (wirelessly or wired) to your computer.
- Scan the "Upload Data" barcode (refer to the full programming manual for specific barcodes). The stored data will then be transmitted to your computer.
3. One-to-Many Transmission
Multiple NT-M2 scanners can transmit data to a single 433MHz wireless receiver, streamlining operations in environments with multiple scanning stations.

This image illustrates how several NT-M2 scanners can simultaneously transmit data to a single USB receiver plugged into a laptop, enabling efficient multi-user scanning.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the scanner's exterior. For the scanning window, use a lint-free cloth lightly dampened with a mild glass cleaner. Do not spray cleaner directly onto the device.
- Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery: For optimal battery life, avoid fully discharging the battery frequently. Charge the scanner regularly, especially if it will be stored for an extended period.
Troubleshooting
- Scanner not connecting wirelessly:
- Ensure the USB receiver is properly plugged into the computer.
- Verify the scanner is powered on.
- Try re-pairing the scanner with the receiver (refer to the full programming manual for pairing instructions, usually by scanning a specific pairing barcode).
- Test the USB receiver in a different USB port or on another computer.
- No data appearing after scanning:
- Check if the scanner is successfully connected (indicated by a beep or LED).
- Ensure an application (e.g., Notepad, Word, Excel) is open and active on your computer to receive the input.
- Verify the barcode is a supported 1D type and is not damaged.
- Adjust the distance and angle of the scanner to the barcode.
- Scanner not reading barcodes accurately:
- Ensure the barcode is clean and clearly printed.
- Check for any obstructions on the scanner's window.
- Try scanning different types of 1D barcodes to isolate the issue.

User Tips
- Scanning Bank Slips: The NT-M2 is capable of reading standard 1D barcodes found on bank slips and similar documents.
- Scanning Through Protection: The laser scanner can often read barcodes through transparent materials like tape or plastic film, but performance may vary depending on the material's thickness and reflectivity.
- Optimal Scanning Angle: For best results, hold the scanner at a slight angle to the barcode, rather than perfectly perpendicular, to minimize glare and improve readability.
