MAGIC WATCH is an ultrasonic reverse warning system. When reversing, it
monitors the space behind the vehicle and provides an audible and visible
warning signal for any obstacles it detects.
Since MAGIC WATCH is designed merely as an additional aid for reversing,
it does not relieve you of the duty to take proper care when reversing.
MAGIC WATCH is designed for installation in small cars.

Functional description

MAGIC WATCH consists of two built-in sensors, a controller, a display for
visual warning signals, and a piezoelectronicspeaker for audible warning sig-
nals. The piezoelectronc speaker is fitted on the parcel shelf or boot cover.
The display can be mounted on the dashboard, on the rear view mirror on the
windscreen or on the boot cover.
It measures distances based on the echo time principle. Both sensors con-
stantly emit ultrasonic signals when you reverse.
The sensors contain both transmitters and receivers, and capture any ultra-
sonic signals reflected by obstacles. The distance to the obstacle is calcu-
lated using the echo time, and signalled by the speaker using a sequence of
impulse tones. The closer the obstacle approaches, the faster the succes-
sion of warning tones.
The display signals the position of the obstacle using two LEDs. A numerical
display shows the distance:
in 10 cm increments if the distance to the obstacle is more than 1 metre
in 2 cm increments if the distance to the obstacle is less than 1 metre
The sensors are installed on the bumper. The sensors may be painted but
not with a multiple-coat paint as this impairs their functionality.
Since the sensors are equipped with their own amplifiers, you can extend the
connection between the sensors and the controller to up to 20 m.
