1.0 - PRELIMINARY ADVICE
Dear customer,
Before installing, identifyyour kit and refer to itfor the correct instructions.
The Caution and Warning signs in this manual provide important notices for installing and using this
product.
Be sure tofollow them in order to ensurea safe and reliable use:
For the user.
This sign highlights useful information or indications regarding the use of the parking
system.
For the installer.
This arious operating modessign indicates v according to connections and
programming of the system or it simply provides useful indications for the installation.

3.0 - SYSTEM OPERATION
USER MANUAL
2.1 - DETECTION ZONES
Detection zones are indicated as “F” (front) and “R” (rear).
Detection zones closest to the obstacle are indicated as “FC” (front) and “RC” (rear)
and displayed as “STOP”.
The STOP zone is the minimum distance detected between an obstacle and the sensor
and in this case the warning tone is solid.
The detection range and the volume of the buzzer can be adjusted (see “setting of
parameters”) according to the needs of the user and the vehicle on which the system is
installed.
The sound alert will vary according to the distance and the detection
zone (front or rear).
stage-by-stage
For the overall functionality of the system, check the programming of all the sensors,
front and rear.
The parking system is designed only as a parking aid, it should not be considered to
replace care and attentiveness while manoeuvring.
Remember to always look around the vehicle while parking.
Small obstacles or objects with low reflectance might not be detected.

inoperative.
One single faulty sensor alters the correct functioning of the whole
parking system.
3.3 - OTHERS
Ice on sensors
Sensors mounted too low
Back part of sensors in contact with frame
Sensors detect external spare wheel
POSSIBLE CAUSE
Clean the sensors
Use the angle brackets (9a or 12) to tilt axe of sensors
upwards
Create a separation between the sensors and the vehicle
(at least 2mm)
Modify the programming of parameter 10 (rear unit)
SOLUTION
2.2 - REAR SENSORS
The rear sensors are activated when reverse gear is engaged; an audible signal
.
Detection of obstacles is signalled by the buzzer and the tone of the buzzer indicates in which
detection zone theobstacle is located.
.
warning will indicate
the sensors areactive
The faster the beeping, the closer theobstacle; a continuous tone indicates the obstacle is extremely
close to thebumper
3.1 - LOW POWER SUPPLY SIGNAL
If, when the control unit is turned on, the battery level is too low to guarantee the accuracy of the
system, the buzzerwill almost immediately give out adeep warning tone for 5”.
This will informthe user thatALL thesensors are deactivated.
The driver willtherefore know that he will haveto do without the parking sensors.
3.2 - FAULTY SENSORS
If, when thecontrol unit is turnedon, one of thesensors turns out tobe inoperative or notconnected,an
audio signal willsound for 3”.
If more than one sensor isinoperative, thenumber of the faulty sensors will be alternatively displayed
on the frontunit (main unit).
2.3 - AUTOMATIC ACTIVATION OF FRONT SENSORS (o )
When ignition is turned ON, the parking system becomes and
Short-pressed (about1 sec.): sensors aredeactivated until thebutton is pressed again.
Long-pressed (about 3 sec., you will hear a beep): sensors remain active until ignition is turned
OFF and ONagain.

dometer signal
stays active as long as the vehicle
speed remains underapprox. 15km/h (set odometer pulses accordingto vehicle, parameter 11).
At speeds above15km/h, the front sensors are disabledand the LED turns off.
The LED turns ON to indicate that the sensors are activate and turns OFF when they are not in
operation.
Press the buttonwith the LED to deactivate thesensors (ex. when in queue).
The push-button canbe:
If thepushbutton is long pressed (when sensors are only temporarily deactivated) they will be completely
disabled until ignitionis turned ON again (ignition OFF-ON).
By means of a specific connection, the system functioning can be inhibited in case of
towing.
4.0 - WARRANTY CONDITIONS
This product is guaranteed to be free from defects in workmanship for a period of 24 months from the
date of installation reported on this warranty, in compliance with the 1999/44/CE Warranty Directive
(L. D. N°24 of the 02/02/2002).
Please fill-in entirely the guarantee certificate included in this booklet and DO NOT REMOVE the
guarantee label fromthe device.
The warranty will become void if labels are missing or torn, if the installation certificate is not fully
compiled or ifthe enclosed sale document is missing.
The warranty isvalid exclusively at authorized Gemini Technologiescenters.
The manufacturerdeclines any responsability for eventualmalfunctions of the parking sensorsor any
damage to thevehicle electrical system due to improperinstallation, use or tampering.
The parkingsystem is strictlya parking assistdevice, it shouldnot be consideredto be asafety device
for any purpose.
5.0 - WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT
(WEEE) DIRECTIVE
The present device does not fall within the scope of Directive 2002/96/EC on Waste Electrical and
Electronic Equipment (WEEE)as specified in art. 2.1 ofL.D. no. 151 of 25/07/2005.
The front sensors can be activated by turning the ignition ON or by pressing the push-button with the
LED.
Operation is parameters.
To activate the sensorsthrough the push-button,press it at the beginning of the manoeuvre; once you
have parked, shortpress the push-button again to deactivatethe sensors.
To deactivate the sensors totally, press and hold the button for at least 3 sec.; a beep confirms the
operation. They will remainswitched offuntil the engine is turnedOFF and ON again.
By modifyingthe of thefront sensors (function12, preset value“00”), the frontsensors will
work as follows:
If, within the preset time, no obstacle is detected in front of the vehicle, the sensors will
automatically be deactivated.
If, within the preset time, the obstacle is stilldetected, the sensors will remain active as long as the
obstacle is detectedand will deactivate 3” after detectingthe last obstacle.
If you need to use the front sensors again after the automatic deactivation, simply press the pushbutton with theLED.
The sensors willautomatically deactivate 3” after detecting thelast obstacle.

(Optional) connect the GREY-RED wire for the “mute” feature to the corresponding wire of the car
radio preset forthis feature.
Plug the terminals with the RED-YELLOW and BROWN wires coming from the rear control unit to
the main controlunit wiring harness connector (5),respectively in positions 17 and5.
Connect the BLACK-BLUE wire of the rear unit wiring harness (8) to the positive of the reverse light
and theBROWN wire tothe metal frame of thevehicle (ground).
Plug the connectors of the sensors wiring to the respective connectors of the control unitsI (4 and

dometer signal
for the programmingof the pulses
To switch off on ly the back sensors, ground pin 19 inside the wiring connector (8) of the
rear control unit; this connection is useful in case of towing.
Automatic inhibition is also possible if the vehicle and the trailer are electrically
connected and an eventual free position is used to ground pin 19 inside the wiring
connector (8) of the rear control unit.
