Fixing Type: Under Bumper Sensor Type: Ultrasonic

What You Get
The Veba under bumper sensors have been cleverly moulded into a triangular shape with a flat mounting plate and screw holes for affixing to the underside of bumpers avoiding the need to drill holes in the bumper or use adhesive sensors. Please note a high sighted bumper is required where the underneath is at least 45cm from the ground. Included with the 4 under bumper sensors is the processor unit and buzzer which gives audible bleeps with increasing frequency as you get closer to an obstacle. Additionally there is an LED display unit which will count down in cm the distance from the sensor nearest an object and 4 LEDs to indicate which sensor is giving the closest reading.

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 Veba's are activated when reverse gear is engaged. As the vehicle is reversed, the digital display counts down the distance from an obstruction. When the vehicle is less than 1.5 metres from the obstruction the audible alert (2 & 4 sensor systems) will emit intermittent bleeps. As the vehicle gets closer to the obstruction the display indicates the reduction in distance and the frequency of the bleeps increases. At 45 centimetres from the obstruction the bleeps become a continuous solid tone.

The Veba recess systems can also be attached to the front of a vehicle for all-round protection. In this instance the power lead needs to be wired into the fuse box rather than the reversing light so that power is always on when the car is in ignition. We suggest the fuse for the car stereo or interior lights.

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.
