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.

Optional Wedge Included
This system comes with an optional wedge, giving greater flexibility according to the shape of your bumper. The wedge 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. If your bumper is vertical, then the wedge can be removed to flush-mount the sensors instead. See pictures below.

Maintenance
No routine maintenance or adjustment is required. Dirt, frost or snow accumulated on the sensors may cause the system to activate incorrectly. Clean carefully with a soft cloth. Do not use chemicals or spirits. Applying hot water in frozen conditions may damage the sensors. The sensors can be washed carefully with warm soapy water
