How does a parking sensor work?
The parking sensor
system is automatically activated when you engage reverse gear. Small sensors are recessed to the rear of the vehicle, they send and receive ultrasonic radio waves, which bounce off obstacles and alert you to their presence. There is an internal buzzer that gradually increases in frequency as you approach the object. A continuous tone denotes that you are within 0.35m (1ft) of the obstacle.

What does the cyue-tech parking sensor kit consist of?
The reverse parking system contains everything you need for a quick and successful installation:
• Central Control Processor
• 2 or 4 Sensors and drill bit

• Internal Buzzer and LED (optional)
• Installation Instructions
