- Page 3 How the System Works The Backup Parking Sensor System determines obstacle distance by measuring the time needed for the ultrasonic wave emitted by a sensor to reach an obstacle and for the sensor to receive the ultrasonic wave reflected from the obstacle. Given the speed of the ultrasonic wave, the system can then calculate and display the distance between the sensor and the obstacle.
- Page 4 Installation and Wiring IMPORTANT: (a) Read this manual thoroughly before proceeding to installation. You can also have the system installed by a professional installer such as your local auto mechanic/auto electrician/car stereo store. (b) Turn off the engine and ACC during installation. (c) Double check that all wiring is correct before powering on the system. (d) During installation, avoid flatting, perforating, cutting, and extending the wires of sensors to reduce unnecessary signal loss.
- Page 5 e) If necessary, smooth the sharp edge of the holes with a polishing head or small round file. f) If you have a non-vertical bumper, you may need to use the wedge-shaped plastic sensor spacers provided. Carefully push each sensor into its sensor spacer. g) Run the sensor wires into the holes drilled.

Page 6: Troubleshooting
Warning To avoid collision with obstacle because of the inertia of vehicle while backing up/parking, keep your vehicle speed at about 3 miles per hour and stop the vehicle immediately once you hear the continuous beeping. This is because even if brake is applied, your vehicle will still go for some distance (inertia) before it comes to a complete stop. - Page 7 IMPORTANT The Parking Sensor Systems sold and distributed by HY Technologies are only a device used to assist a driver while parking. They should not be considered as a substitute for driver responsibility when operating a vehicle. No warranty as to operational efficiency is granted. We don't guarantee or assume liability for collisions or damages that take place when parking your vehicle with the use of the Parking Sensor System.
