5. Instrucciones de funcionamiento
5.1 Escaneo básico
To scan a barcode, point the scanner's laser window at the barcode and press the "SCAN" button. The scanner will emit a laser line and a confirmation sound/vibration (if enabled) upon successful scan. The scanned data will appear on the display.
5.2 Modos de escaneo
El escáner admite tres modos de escaneo principales:
- Modo de disparo clave: Press the SCAN button for each barcode scan.
- Modo de escaneo continuo: The scanner continuously emits the laser and scans barcodes without needing to press the button for each scan.
- Modo de detección automática: The scanner activates the laser and scans when a barcode is detected within its field of view.
Refer to the included quick start guide or the full manual (if available from the manufacturer) for specific barcodes to switch between these modes.

Figura 5.2.1: Encimaview of the three available scanning modes.
5.3 Modos de carga de datos
The scanner offers two data transmission modes:
- Modo de carga instantánea: Barcode data is transmitted immediately to the connected device after each scan.
- Modo de almacenamiento sin conexión: Barcode data is stored internally in the scanner's memory (up to 50,000 barcodes) and can be uploaded later to a connected device.
To switch between these modes, press buttons 1 and 2 simultaneously. Consult the product's configuration guide for detailed instructions on managing stored data.

6.2 Conexión inalámbrica 2.4G
Para conectarse mediante conexión inalámbrica 2.4G:
- Plug the provided USB wireless dongle into an available USB port on your computer.
- Ensure the scanner is in 2.4G wireless mode (usually by scanning a specific barcode in the manual).
- The scanner and dongle should automatically pair. The scanner's display will indicate a successful 2.4G connection.
2.4G wireless range is approximately 30m (98ft) in a barrier environment and 150m (492ft) in a barrier-free environment.
6.3 Conexión por cable USB
To connect via USB cable:
- Conecte el escáner a su computadora mediante el cable USB-C.
- The scanner will function as a wired device, and data will be transmitted directly. This mode also charges the device.

Figura 6.3.1: Wireless Connectivity Ranges.
7. Display Screen Management
The 1.5-inch LCD screen provides real-time information and configuration options:
- Scanning Time: Muestra la hora actual.
- Estado de conexión: Indicates whether the scanner is connected via Bluetooth, 2.4GHz wireless, or USB wired.
- Nivel de energía de la batería: Muestra la carga restante de la batería.
- Datos del código de barras: Displays the last scanned barcode.
- Stored Data Amount: Shows the number of barcodes stored in offline mode.
- Total Scanning Amount: Tracks the total number of scans.
Advanced configurations, such as displaying goods names and prices, require uploading specific information to the scanner using a dedicated tool. Contact Symcode support for assistance with this feature.
8. Batería y gestión de energía
The scanner is equipped with a 2000 mAh Lithium Polymer battery. A full charge provides approximately 30 days of standby time and 5-7 days of frequent use. The display screen includes a battery level indicator. Charge the device when the battery level is low to ensure uninterrupted operation.
The separate physical switch button helps reduce power loss when the device is not in use.
9. Mantenimiento
- Limpieza: Use a soft, dry cloth to clean the scanner's exterior. For the scanning window and display, use a soft, lint-free cloth lightly dampened with water or a mild screen cleaner. Avoid abrasive materials or harsh chemicals.
- Almacenamiento: Guarde el escáner en un lugar fresco y seco, alejado de la luz solar directa y de temperaturas extremas.
- Cuidado de la batería: Para un almacenamiento prolongado, cargue la batería aproximadamente al 50 % para prolongar su vida útil. Evite descargarla completamente durante períodos prolongados.
10. Solución de problemas
10.1 El escáner no se enciende
Ensure the battery is charged. Connect the scanner to a power source using the USB-C cable and allow it to charge for at least 30 minutes before attempting to power it on again.
10.2 No se pueden escanear códigos de barras
- Verify the scanner is powered on and the laser is active when the scan button is pressed.
- Asegúrese de que el código de barras esté limpio, sin daños y dentro del rango y ángulo de lectura del escáner.
- Check if the correct scanning mode is selected (Key Trigger, Continuous, or Automatic Sensing).
- Confirm the barcode type is supported (this is a 1D scanner).
10.3 Connection Issues (Bluetooth/2.4G Wireless)
- Bluetooth: Ensure Bluetooth is enabled on your host device and the scanner is in pairing mode. Try unpairing and re-pairing the device.
- 2.4G inalámbrico: Ensure the USB dongle is securely plugged into the computer and the scanner is in 2.4G mode. Try re-plugging the dongle.
- Move closer to the host device to rule out range issues.
- Check the scanner's display for connection status indicators.
10.4 Scanned Data Not Appearing on Host Device
- Verify a successful connection between the scanner and the host device.
- Ensure the scanner is in "Instant Upload Mode" if you expect immediate data transmission. If in "Offline Storage Mode," you will need to manually upload the stored data.
- Check that the cursor is active in a text field or application on your host device where you expect the barcode data to appear.
