4. Configuración e instalación
4.1 Sensor Placement and Drilling
The ultrasonic probes are designed for embedded installation. Use the provided 22mm hole opener to drill precise holes in your vehicle's bumper for a flush fit. Ensure sensors are placed symmetrically and at an appropriate height for optimal detection.

The probes feature a plane double-angle design to optimize detection. Refer to the diagram for recommended horizontal and vertical angles. The probe size is 22mm in diameter and 18.5mm in height.

4.2 Método de cableado
Connect the power cable to your vehicle's electrical system as follows:
- Fío amarelo: Connect to the reverse light positive.
- Fío branco: Connect to the brake light positive.
- Fío vermello: Connect to ACC positive (Accessory power).
- Fío negro: Connect to negative (ground).
Ensure all connections are secure and properly insulated. Incorrect wiring may damage the system or vehicle electronics.

5. Instrucións de funcionamento
The parking radar system automatically activates when the reverse gear is engaged. It provides real-time distance readings and audible alerts to guide you during parking maneuvers.
5.1 LCD Display Functionality
The color LCD display provides clear visual feedback:
- Lectura dixital: Shows the precise distance to the nearest obstacle in centimeters.
- Orientación: Indicates the direction of the obstacle (left, center, right) relative to the vehicle.
- Dynamic Picture: A graphical representation of your vehicle and surrounding obstacles.
- Sound/Buzzer: Provides step-by-step audible alerts that increase in frequency as you approach an obstacle.

The system's dual CPU ensures fast response times and accurate digital display. A probe self-test function alerts you to any abnormal sensor status, preventing false readings due to damage.

6. Mantemento
To ensure optimal performance and longevity of your parking radar system, follow these maintenance guidelines:
- Clean Sensors Regularly: Keep the ultrasonic probes clean from dirt, mud, snow, or ice. Obstructions can interfere with detection accuracy. Use a soft cloth and mild cleaning solution.
- Inspeccionar o cableado: Periodically check all wiring connections for any signs of wear, fraying, or corrosion. Ensure they remain secure.
- Avoid High-Pressure Washing: When washing your vehicle, avoid directing high-pressure water jets directly at the sensors, as this may cause damage.
- Protección ambiental: The system is designed to withstand various temperatures (-40 to +80 °C), but extreme conditions can still impact performance.
7 Solución de problemas
If you encounter issues with your parking radar system, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| Sen pantalla nin alimentación | Conexión eléctrica solta, fusible fundido, cableado incorrecto. | Check power cable connections. Inspect vehicle fuse box. Verify wiring against Section 4.2. |
| Lecturas de distancia inexactas | Dirty/obstructed sensors, damaged sensor, extreme weather. | Clean sensors. Check for physical damage to sensors. Allow system to normalize in stable temperatures. |
| Constant beeping/false alarms | Sensor obstruction, faulty sensor, electromagnetic interference. | Ensure sensors are clear. Check for loose sensor connections. The system has super anti-electromagnetic interference, but extreme sources can still cause issues. |
| A pantalla mostra "Erro" | Sensor malfunction detected by self-test function. | Identify the faulty sensor (if indicated) and replace it. Check sensor wiring. |
