Be very careful when you first operate the device, and make sure that you familiarize yourself with the various sequences of beeps. Zone Description (see fig. 5, page 5) Sound sequence LEDs 42 1 MagicWatch recognises obstacles at a distance of around 1.2 m (measured from the sensor) and signals them with a series of slow beeps from the speaker and by the illuminating the green LED. 2 At a distance of around 0.8 m (measured from the sensor) MagicWatch switches to the orange LED and to a mediumlength beep sequence. 3 At a distance of around 0.4 m (measured from the sensor) and less, MagicWatch switches to the red LED and a continuous tone. When you reach this zone, stop the vehicle. Otherwise you might damage the vehicle or the obstacle. Beep Beep Beep Beep Beep Beep Beep Green Orange Beeeeep… Red In Zone 3 some obstacles may not be detected, because they are no longer within range of the sensors (construction-related characteristic). MagicWatch is equipped with a diagnostic function. If a sensor fails, the display indicates the error by quickly flashing the respective red LED (e. g. left red LED to indicate the left sensor).

A short double beep sounds to indicate that it is working. Once an obstacle is in the detection range, the distance is indicated by the various LED colours. A sequence of warning signals is sounded in addition. As you approach the obstacle when driving in reverse, the colours of the LEDs change as does the speed of the sound sequence. MagicWatch differentiates between three distance categories (see Chapter “Performing a functional test” on page 42). Each LED represents a sensor. If the right edge of the vehicle approaches an obstacle, the LED on the right signals the obstacle. If the obstacle is detected by the middle sensors, the middle LEDs light up etc. The LED colours represent the distance ranges shown below: LED Distance Green approx. 1.2 – 0.8 m Orange approx. 0.8 – 0.4 m Red approx. 0.4 – 0 m Caution! Stop the vehicle immediately and investigate the situation (getting out if necessary), if the following happens while you are reversing: The device first shows an obstacle while you drive in reverse, and the beeps speed up as normal (i.e. from slow to medium). Suddenly the beeping sound slows down, or no obstacle is shown at all. This means that the original obstacle is in the blind spot of the sensors (construction-related characteristic), and it is possible to hit it. 43
