Small objects or those with poor reflective characteristics may not be detected. Zone 2 Nearly all objects are displayed in this zone. Zone 3 Virtually all objects are displayed in this zone, but some objects may come into the blind spot of the sensors. 34 Situations may arise where MagicWatch does not detect objects or fails to signal their distance correctly, due to their physical characteristics. Note the four following examples. Example 1 (see fig. 6, page 5) Objects which are not in the detection area of the sensors from the very start cannot be detected. Example 2 (see fig. 7, page 5) When moving towards an object with an irregular or jagged surface, the shortest distance to the object may not be signalled. In the example, A is not signalled, but only B or C instead. Example 3 (see fig. 8, page 5) For diagonal obstacles, the shortest distance A is signalled. Example 4 (see fig. 9, page 6) In this case, MagicWatch displays the distance A. As the vehicle approaches, the audible indicator changes to the stop signal. As the vehicle approaches even further, the distance A goes into the blind spot, so that MagicWatch signals the distance from point B.

As these four examples show, situations can arise where the device fails to display an object or does not display the shortest distance. The device does not relieve you of your obligation to take special care when reversing. Therefore, always be extremely careful when reversing. If an object enters the blind spot of the sensors, MagicWatch automatically shows the distance to the next object. This means the piezo speaker changes from fast to medium beeps and the display shows a different distance. In this case, always stop the vehicle immediately and investigate the situation. 5.3 Control elements The control box has the following control elements: No. in fig. 10, page 6 Meaning 1 Connection for the connecting cable to the display. 2 Connection for the for sensor cables. Observe the designation on the sensor cable and on the main unit. 3 Control for adjusting the sensor sensitivity. Turn the control clockwise to increase the sensitivity. 4 Supply line connection. 35
