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

The 4 rear sensors work of the reversing lights power supply and switch on automatically when reverse gear is selected. The front sensors power off the brake lights and power up whenever the brake pedal is applied. The front sensors will remain on for 5 seconds after you stop braking. When both sets of sensors are in operation either because you are braking while reversing or you start reversing after braking then the rear sensors take precedent over the front sensors.

For the rear sensors, 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.

For the front sensors alerts will only start at a shorter range of 1m to avoid false alerts from other cars when queuing in traffic.

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----------

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
