- The sensors emit short pulses of ultrasound waves, which then rebound from obstacles within their field of view. The rebounded signals are then received again by the sensors. The central control units then evaluates the time delay of the rebounded signals and interprets the distance of an obstacle.
- Two 18mm diameter ultrasonic sensors are installed into the front bumper.
- Once reverse gear is selected the main control unit provides distance information via a small speaker and L.E.D., which is mounted inside the vehicle.
- Initial tones confirm the selection of reverse gear, as the vehicle reverses nearer to an obstacle the tones become more frequent and remain constant at approximately 30cm from the obstacle.
- Internal speaker volume is adjustable between high and low.
- Diagnostic feature.
- External sensors can be colour coded if required, without affecting the performance of the system.
