How it works
The system works by radiating ultrasonic beams covering the area behind the vehicle. The beams are reflected by obstructions behind the vehicle, and re-enter the sensors. The reflected beam information is processed to calculate the distance of the obstruction.
As with the other systems the Dolphin unit is activated when reverse gear is engaged. As the vehicle is reversed. When the vehicle is less than 1.5 metres from the obstruction the audible alert will emit intermittent bleeps. As the vehicle gets closer to the obstruction the frequency of the bleeps increases. At 30 centimetres from the obstruction the bleeps become a continuous solid tone.
| Stage | Distance | Awareness | Alarm |
| 1 | 200 - 160cm | Safe Mode | No |
| 2 | 150 - 100cm | Safe Mode | Bi----Bi----Bi |
| 3 | 90 - 50cm | Alarm Mode | Bi--Bi--Bi |
| 4 | 40 - 30cm | Danger Mode | Bi-Bi-B |
| 5 | 30 - 0cm | Stop | Bi---------- |

| Swap Socket Feature All the dolphin kits now come with the new watertight swap socket feature based 6 inches from the sensor heads, it makes installation quicker and easier. Also should you ever have a problems with accident damage in the future it facilitates easy replacement without having to remove the bumper again and rewire from scratch. |
Optional Wedges
This system comes with optional angled wedges, giving greater flexibility according to the shape of your bumper. The wedges can be used if your bumper is slightly angled up - or downwards, to ensure the sensor's signal is still sent out parallel with the road's surface.
