Testing functions
Conduct the functional test as follows:
➤ Switch on the ignition and engage reverse gear.
The MWE-250-3 reverse warning system does not have a visual display, it
only has an acoustic warning signal. Be very careful when you first operate
the device, and make sure you get to know the various sequences of beeps.
Zone Description (see fig. 5, page 5)
1
MagicWatch recognises obstacles from a
distance of around 1.5 m (measured from
the sensor) and signals them with a series
of slow beeps from the speaker.
2
From a distance of around 0.95 m
(measured from the sensor)
MAGIC WATCH switches to the medium
sequence.
3
At a distance of around 0.4 m (measured
from the sensor) and below, MagicWatch
switches to the continuous tone. When you
reach this zone, stop the vehicle.
Otherwise you might damage the vehicle
or the obstacle.
In Zone 3 it can occur that obstacles are not detected, because
they are no longer within range of the sensors (depending on
design).
The device is equipped with a diagnostic function: If the sensors are defec-
tive, you will hear three short beeps when you engage reverse gear.
