  • Page 2 Features & Specifications If you have problems parking then this kit is for you. Using (ultrasonic) sound waves, whose frequency is beyond our range of hearing, we can "measure" a distance. Consequently, a sensor mounted at the back of the car can give an indication of the distance between your car and the car parked behind you or other obstacles (only at the same height as the sensor).
  • Page 3 Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip.
  • Page 4 REMOVE THEM FROM THE TAPE ONE AT A TIME ! AXIAL COMPONENTS ARE TAPED IN THE COR- RECT MOUNTING SEQUENCE ! You will find the colour code for the resistances and the LEDs in the HALG (general manual) and on our website: http://www.velleman.be/common/service.aspx...

    Test 3. TEST Connect the points GND, +V, RW, DIS, S1 and S2 of the main PCB to the corresponding points on the receiver PCB. Make sure that the distance between the receiver print and the base print is approx. 50cm. Adjust the trimmer RV1 at the middle position RV1.
  • Page 10 Installation Install the print behind the bores using spacing sleeves, so that the sensors are facing the bores properly without touching the housing. Fig. 1 Fig. 2 B) With the sensors in horizontal position (fig. 2): In this case the sensors are simply mounted on the print. Now realise the gaps in the housing as shown on the drawing 4.0 Install the print behind the bores using spacing sleeves, so that the sensors are facing the bores properly without touching the housing.

Surch for a suitable place somewhere in the trunk, to built in the base print (by preference as close as possible to the sensor, see below) Find a suitable place, approximately in the middle of the backside of the car, for installing the sensors f.i.
  • Page 12 Connection & use 5. DEFINITIVE CONNECTION Connect the receiver to the base print. Connect the terminal GND of the base print to the - of the car (chassis) Connect the terminal ‘+’ of the base print to the ‘+’ of the reverse light. 6.
