Introduction
The MACHSWON 8-Sensor Car Parking Radar Kit is designed to assist drivers in safely parking and maneuvering their vehicles by detecting obstacles in front and behind the car. This system provides visual and audible alerts, helping to prevent potential collisions with pedestrians, other vehicles, and low-lying objects.
This kit includes a main control unit, an LED display with a buzzer, and eight ultrasonic sensors for comprehensive coverage.

Installation Guide
Professional installation is recommended for optimal performance and safety. Ensure the vehicle's power is disconnected before beginning installation.
1. Sensor Placement
The kit includes eight sensors: four for the front bumper and four for the rear bumper. Proper placement is crucial for accurate detection.
- Rear Sensors: Mount four sensors evenly spaced on the rear bumper. Ensure they are positioned between 50-70 cm (approximately 20-28 inches) from the ground.
- Front Sensors: Mount four sensors evenly spaced on the front bumper.
- Angle: Sensors should be installed at a 90-degree angle to the ground. Avoid angles that might cause false readings or reduce detection effectiveness.

2. Wiring Connections
- Connect the eight ultrasonic sensors to the main control unit using the provided wire harness. Ensure each sensor is connected to its corresponding port (A, B, C, D for rear; E, F, G, H for front, or as indicated on the unit).
- Connect the LED display to the main control unit.
- Connect the main control unit's power cable to the vehicle's electrical system.
- The rear sensors are activated when the vehicle is in reverse gear. Connect the power wire for the rear sensors to the reverse light circuit.
- The front sensors are activated when the foot brake is applied. Connect the power wire for the front sensors to the brake light circuit or a suitable ignition-switched power source that activates with braking.
- Secure all wiring to prevent interference or damage.
3. Testing the System
After installation, perform a thorough test:
- With the vehicle in reverse, slowly approach an obstacle. The rear sensors should activate, and the LED display should show the distance, accompanied by an audible buzzer. The alarm sound will become louder and faster as the obstacle gets closer.
- With the vehicle stationary, apply the foot brake. The front sensors should activate, and the LED display should show any obstacles in front, with corresponding audible alerts.
- Ensure all connections are secure and the system functions as expected in both braking and reversing states.
Operating Instructions
The MACHSWON Parking Radar Kit operates automatically based on vehicle actions:
- Rear Sensor Activation: When the vehicle is shifted into reverse gear, the four rear sensors automatically activate.
- Front Sensor Activation: When the driver applies the foot brake, the four front sensors automatically activate.
- Visual Display: The LED display shows the distance to the nearest obstacle. The display color may change (e.g., green, yellow, red) to indicate proximity.
- Audible Alarm: An integrated buzzer provides an audible warning. The frequency and volume of the beeps increase as the vehicle gets closer to an obstacle.
- Buzzer Control: The system includes a switch to turn the buzzer alarm on or off, allowing for silent operation if preferred.
Always use the parking radar system as an aid and not as a substitute for careful driving and visual checks. Blind spots can still exist, and environmental factors may affect sensor performance.
Maintenance
To ensure the longevity and optimal performance of your parking radar system, follow these maintenance guidelines:
- Sensor Cleaning: Regularly clean the ultrasonic sensors to remove dirt, mud, snow, or ice. Obstructions on the sensor surface can impair detection accuracy. Use a soft cloth and mild cleaning solution.
- Wiring Inspection: Periodically check all wiring connections for signs of wear, corrosion, or looseness. Secure any loose connections.
- Avoid High-Pressure Washing: When washing your vehicle, avoid directing high-pressure water jets directly at the sensors, as this could damage them.
- Environmental Factors: Be aware that extreme weather conditions (heavy rain, snow, fog) or certain road conditions (gravel, uneven surfaces) may temporarily affect sensor performance.
Troubleshooting
If you experience issues with your parking radar kit, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not power on. | No power supply; loose wiring; blown fuse. | Check power connections to the main control unit. Ensure wiring is secure. Inspect vehicle's fuse box for a blown fuse related to the parking system. |
| Sensors not detecting obstacles or giving false alarms. | Sensors are dirty or obstructed; incorrect installation angle; faulty sensor. | Clean sensors thoroughly. Verify sensors are installed at a 90-degree angle. Check for any physical damage to sensors. If problem persists, a sensor may need replacement. |
| Buzzer alarm is not sounding. | Buzzer is switched off; faulty buzzer/display unit. | Check the buzzer on/off switch on the LED display. Ensure the display unit is properly connected. |
| Inconsistent detection range. | Environmental interference (rain, snow); sensor calibration issue. | Performance may vary in adverse weather. Ensure sensors are clean. Re-check installation for proper angle and secure mounting. |
