detection.
•
If sensitivity is not correct, adjust the
trimmer again and repeat operations
from the start.
•
If the adjustment carried out is correct,
position the module 5123 definitively.
Super-high frequency module connection and
positioning
Connection is simple since, the connector corre-
sponding to that present in the ultrasound module
is fitted in the alarm cable harness.
Join the 4-way connector of the alarm cable har-
ness to the 4-way connector of the super-high
frequency.
The sensor operates based on the principle of re-
flection of the high-frequency electromagnetic
waves by conductive objects (metals, human
body, etc.).
Measuring the magnitude of these reflections al-
lows detecting any foreign object moving within the
electromagnetic field, thus causing an alarm sta-
tus.
The characteristics of sensor 7059 render it unaf-
fected by air fluctuations (for example: wind, tur-
bulence, thermal variations, etc.), therefore it is
particularly suitable to be fitted on cabriolet vehi-
cles or vehicles with sunroof.
Permeability to electromagnetic waves of non-
conductive materials (plastic, fabrics, etc.) permits
