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 40 centimetres from the obstruction the bleeps become a continuous solid tone.
