PROXIMITY ELECTRONICS
INSTALLATION INSTRUCTIONS & USER MANUAL
The sistem is strictly a driver assistance device and should not be relied upon as a
security device or a substitute for safe driving practices.
Use common sense when reversing and always follow recommended safe driving guidelines.
EPS-DUAL 2.0 can be installed only on rear bumper.
a) The installation of the antenna sensor, constituted by an
aluminium adhesive ribbon, must be applied to the inner surface of the
bumper. It is of some importance that the zone of application corresponds
to the higher part as regards the ground but also the most distant from the
car body. It is not advisable to install the antenna sensor too low.

b) Disassemble the bumper.
Correct zone
STARTING PROCEDURE
a) Identify on the car body the zone close to the extremity of the bumper and, on
the side where it is present the back-gear lamp, a possible hole of passage
toward the intern of the trunk in order to carry on the RF cable from the antenna
sensor.
b) Through the individuated passage route the RF cable inside the trunk
leaving the fast-on terminal outside. (Fig. 2)

MOUNTING THE ANTENNA SENSOR
Thoroughly clean with alcohol or nitre solvent (be careful not to use anti-
adhesive detergent) the inner surface of the bumper of the zone previously
identified (see Fig.1) on which will be applied the antenna sensor.
Starting from the zone where there is the RF cable , start applying the adhesive
aluminium tape (antenna sensor) practising a good pressure to make it well
adhere to the inner surface of the bumper *.

RF Cable
Connect the RF Cable coming from the ECU to the antenna sensor.
Apply a piece of sticking material on the connection and fix it on the bumper by
a strong pressure (If the ambient temperature is below 10 °C we recommend
heating both the mastic and the sticking area on the bumper). It is necessary to
use the same material to fix the opposite extremity of the antenna. (Fig. 5).
Replace the bumper and pull the RF Cable inside the luggage compartment in
order not to leave excess cable outside.

c) Insert all plug-in connectors into the proper position on the Central Unit (ECU)
as in Fig. 6.
Some vehicles are equipped with a metal crash protection bar insert facing the
inside surface of the bumper. When this metal surface is too close to the inner
surface of the bumper where you have placed the antenna sensor, the distance
signal can be reduced.
To adjust the signalling distance it is sufficient to change the dip-switch positions
(see schematic). Take care that the sensitivity No 1 is the lowest and the number
4 is the largest.
The sensibility that we recommend for most cars is the No. 2.
We suggest to carry out tests to determine the detection range, pointing out that
increasing the sensibility where it is not necessary, can cause more false alerts.
MOUNTING THE BUZZER
a) Mount the EPS-DUAL 2.0 speaker using its adhesive in a proper place in
order to ensure a good perception of sound by the driver.
FINAL TESTING PROCEDURE
a) Turn on the key, insert the back gear. In a fraction of second the control unit
performs a check of the functionality of the system and, if everything has been
done correctly, the buzzer emits an acoustic sound of "OK" (two notes in rapid
succession). Once you have this signal the system becomes operational.
Possible problems and their solutions
1. If the acoustic transducer does not emit any signal check all the connections.
2. If the transducer emits an audible warning signal consisting of 2 notes (one
high and one low repeated 3 times) check the connection of RF cable to Central
module (ECU).
3. If the buzzer produces 6 consecutive fast beeps control the RF cable and its
connection to the control unit and that there is not a short circuit on the RF cable
or between the antenna sensor and the metal body of the car.

ENG When the antenna sensor has been attached, covering the whole of the
______bumper from left to right, the excess length is cut off. Place a piece of the
______included sticking material at either ends of the antenna sensor to ensure
a secure fixing onto the bumper surface.
It is recommended (but not essential) to cover the antenna with a black anti-rust
protection paint of the same type that is applied to the underneath of a car
chassis or similar to protect from the elements (do not use silicon paste).

1) It is important to start and
finish the application of the
tape to about 15 cm from
both ends of the bumper
2) The antenna sensor can
not be applied on metal
bumpers.

b) Starting from about 1 meter away from the center of the bumper, slowly
approach both hands to simulate a parking maneuver. At a distance of about
60/70 cm will be heard the first acoustic signals whose repetition rate will
increase at the decreasing distance to become a fast intermittent sound and
then a continuous higher frequency sound at about 10-15 cm from the bumper.
WARNING: For a correct simulation be careful to reset the system every time
you approach.
c) If the system shows to work regularly it is possible to fix definitely the bumper.
Note: EPS-DUAL 2.0 starts to give the signalling only when the vehicle is
being approached to the obstacle; a fixed object in front of the bumper, for
instance the hauls hook and a bull bar or the sides walls of a car box, is not
signalled and it is not bothered the normal operation of the device.
USER MANUAL
OPERATING PRINCIPLE
EPS-DUAL 2.0 is an innovative parking sensor that uses low energy
electromagnetic waves and is able to detect the approach of any kind of
obstacle.
The activation of the device is obtained by the insertion of the back gear and
confirmed by a signal of “OK". Once activated, the EPS-DUAL 2.0 generates
around the bumper, on which is installed, a protection zone (Fig. 6).
When any obstacle present in the protection zone tends to approach the
bumper you will hear a series of beeps.
WORKING EXAMPLE
A) As soon as the EPS-DUAL 2.0 is activated the control functionality of the
system is carried out in a fraction of second.
In case of anomalies the speaker emits an audible warning signal consisting of 2
notes (one high and one low) repeated 3 times. If this happens check the
connection of RF cable to Central module (ECU).
If the control is OK you hear a signal of two notes in rapid succession to confirm
the proper functioning of the system.
B) When approaching an obstacle the system activates the acoustic signal at
a distance between the bumper and obstacle (measured in the central area
of the bumper) of about 60 / 70 cm with 3 types of sounds:
1) an increase in sequence of "BIP" (alert) informs the driver that an
obstacle is approaching.
2) intermittent sounds of fast repetition rate when the obstacle comes
close to the bumper at a distance between 15 and 30 cm measured on the
middle of bumper (alarm).
3) continuous sound at a more acute frequency (risk of contact) when
an obstacle is very close to the bumper (10-15 cm).
Note:
- The distances will vary depending on the size of the obstacle and
correspond to the central zone of the bumper; on the lateral edges the
distances is less (see Figure 6)
- The alert occurs only when the vehicle is approaching an obstacle, a fixed
object in front of the bumper is only detected after the first movement of
approach.
WARNING
1. In presence of rain or high moisture weather, the system reduces his
sensibility automatically in order to eliminate a part of false alarms that could be
given by movement of water on the bumper.
2. As soon as the system is activated an acknowledgement of the
surrounding of the bumper is made.
Consequently , during testing operation, not to switch on it is very important
the system while you are very close to the central unit and antenna sensor in
order not to have false information on the working capability of the system.
During the test you must also take into consideration the fact that, after the first
approach to the bumper, any subsequent APPROACH without first reset the
system, can give false interpretations of the functionality of the sensor due to
special characteristics of the EPS-DUAL 2.0 software specifically created to
reduce false signalling in the rainy conditions.
