How it works
The system works by radiating ultrasonic beams covering the area infront of the vehicle. The beams are reflected by obstructions ahead, and re-enter the sensors. The reflected beam information is processed to calculate the distance of the obstruction.

With the Dolphin Display Front Parking Sensors you need to power them via a small toggle switch on the dashboard which is included with the kit. Then you manually turn the sensors on, as and when you need to use them. Alternatively you could have them permanently powered on since there is an audio on/off switch on top of the display. 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.

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 - 0cm	Danger Mode	Bi----------

This is an example of the display in action. If you had a post just on one side of the car the illuminated bars would vary and the shorted distance reading would be displayed.

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
