3. Setup
3.1. Charging the Device
Before first use, fully charge the MT850 scanner. Connect the provided USB-mini cable to the scanner's charging port and the other end to a USB power adapter or a computer's USB port. The charging indicator light will show the charging status.
3.2. Initial Bluetooth Pairing
- Ensure the MT850 scanner is powered on.
- Activate Bluetooth on your host device (smartphone, tablet, or computer).
- On your host device, search for available Bluetooth devices. The MT850 will appear as 'MT850' or a similar identifier.
- Select 'MT850' to initiate pairing. Bluetooth 5.0 allows for quick pairing without requiring a PIN code.
- Once paired, the scanner will emit a confirmation beep, and the Bluetooth indicator light will stabilize.
The MT850 supports both HID (Keyboard Emulation) and SPP (Virtual Serial COM) modes. The default mode is typically HID, which allows the scanner to act as a keyboard input device. For SPP mode, refer to the advanced configuration guide.
4. Operating the Scanner
4.1. Basic Scanning Operation

Figure 4.2: The MT850 scanner in use, scanning a barcode on a large package, illustrating its utility in logistics and inventory management.
- Point the scanning window of the MT850 towards the barcode you wish to scan.
- Press and hold the trigger button. An aiming beam will be projected onto the barcode.
- Position the scanner so the aiming beam covers the entire barcode.
- Once the barcode is successfully read, the scanner will emit a beep and/or vibrate (if vibrator is enabled), and the data will be transmitted to the connected host device.
- Release the trigger button.
4.2. Batch Data Collection Mode
The MT850 can store scanned data internally when not connected via Bluetooth or when operating in batch mode. To activate batch mode, refer to the specific configuration barcodes in the full user manual. In batch mode, scanned data is saved to the scanner's 2MB memory. To upload the stored data, connect the scanner to a computer via USB and use the provided utility software, or switch back to online mode and transmit the data.
5. Maintenance
5.1. Cleaning
To maintain optimal performance, keep the scanning window and the device's exterior clean. Use a soft, lint-free cloth lightly dampened with water or a mild, non-abrasive cleaning solution. Do not use harsh chemicals or abrasive materials, as they may damage the device. Ensure no liquid enters the device's ports.
5.2. Storage
Store the MT850 in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, ensure the battery is partially charged (around 50%) to prolong its lifespan.
6. Troubleshooting
- Scanner not powering on: Ensure the battery is charged. Connect the scanner to a power source using the USB-mini cable.
- Cannot pair via Bluetooth: Make sure Bluetooth is enabled on both the scanner and the host device. Ensure the scanner is in pairing mode (refer to the full manual for specific instructions if needed). Try restarting both devices.
- Barcode not scanning: Ensure the barcode is clean and not damaged. Adjust the distance and angle of the scanner to the barcode. Check if the aiming beam is properly covering the entire barcode. Verify that the scanner is in the correct operating mode (e.g., HID for direct input).
- Scanned data not appearing on host device: Confirm that the Bluetooth connection is active. Check if the host device's input field (e.g., text editor, spreadsheet) is active and ready to receive input.
- Device unresponsive: Perform a soft reset by holding down the trigger button for an extended period (e.g., 10-15 seconds) or by disconnecting and reconnecting the battery if accessible (refer to the full manual for specific reset procedures).
