For the overall functionality of the system, check the programming of all the sensors,
front and rear.
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).

1.0 - PRELIMINARY ADVICE
Dear customer,
Before installing, identify your kit and refer to it for the correct instructions.
The Caution and Warning signs in this manual provide important notices for installing and using this
product.
Be sure to follow them in order to ensure a safe and reliable use:

2.0 - SYSTEM OPERATION
USER MANUAL
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.

To time-activate the sensors, a parameter must be be modified (see chapter “setting of
parameters).
When the setting is modified, the OFF sign is not displayed when the left hand side
push-button is pressed because the sensors will automatically activate when ignition is
turned on again.
Engagement of the reverse gear activates the rear sensors but also the front sensors if
they are programmed to work on a “time-activation” basis.
On some vehicles, when speed exceeds 10Km/h, no icon could be displayed even
though the system is active.
The sensors can still be deactivated with the push-button.
The front sensors are activated by turning on ignition; an upward arrow icon will light up on the display
to indicate activation.

By modifying the of the front sensors (function 13, ), the front sensors
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 still detected, the sensors will remain active as long as the
obstacle is detected and will deactivate 3” after detecting the last obstacle.
If you need to use the front sensors again after the automatic deactivation, simply press the left
push-button.
The sensors will automatically deactivate 3” after detecting the last obstacle.

2.2 - REAR SENSORS
The rear sensors are activated when reverse gear is engaged; an audible signal
.
To reactivate them, simply press the same button
warning and the
downward arrow icon that lights up on the display will indicate the sensors are active.
Obstacles are signaled by different audible tones and the lighting up of the relative detection zones
and distance on the display.
The faster the beeping, the closer the obstacle; a continuous tone indicates the obstacle is extremely
close to the bumper.
To deactivate the sensors (when reverse gear is engaged), simply press the push-button on the right
hand side of the display; the “OFF” sign will light up on the bottom part of the displayed vehicle and the
downward arrow will turn off to indicate the sensors are deactivated
.
In case of need (vehicles in queue), press the push-button with the upward arrow to deactivate the
sensors.
In this case the “OFF” sign will light up on the displayed vehicle.

AUTOMATIC ACTIVATION OF FRONT SENSORS (odometer signal)
Front sensors are activated whenever ignition is turned ON and are automatically deactivated when
speed exceeds about 15Km/h

after a few seconds, the following icons will be displayed: vehicle, front sensors arrow icon and four
front detection zones closest to the bumper.
The arrow and the detection zones icons will flash for about 8/10 seconds.
This will inform the driver that ALL sensors are deactivated and that he will have to carry out reversing
and parking manoeuvers without the help of the sensors.
When nominal tension is restored, the rear sensors will start working normally.

If parameter 13 has not been modified and is set to “0”, the front sensors arrow and detection zones
will flash as long as the control unit remains active.
If, on the other hand, parameter 13 has been modified, the front sensors arrow and detection zones
will flash for about 8/10 seconds.
All other sensors will operate normally.
If one of the rear sensors turns out to be inoperative when reverse gear is engaged, the front sensors

(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 of L.D. no. 151 of 25/07/2005.
6.0 - 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 from the device.
The warranty will become void if labels are missing or torn, if the installation certificate is not fully
compiled or if the enclosed sale document is missing.
The warranty is valid exclusively at authorized Gemini Technologies centers.
The manufacturer declines any responsability for eventual malfunctions of the parking sensors or any
damage to the vehicle electrical system due to improper installation, use or tampering.
The parking system is strictly a parking assist device, it should not be considered to be a safety device
for any purpose.
In areas with high RF disturbances, the antenna icon will light up on the display and a
ticking sound will be heard.
If the disturbance affects the rear control unit, it will deactivate within a few seconds (the
downward arrow icon will turn off).
If the disturbance affects the front control unit, it will deactivate within a few seconds
(the upward arrow icon will turn off) but the continuous “STOP ZONE” alert will sound.
Press the left push-button on the display to stop the beeping and deactive the sensors.
This procedure can only be done if the relative cable of the display wiring is connected
to the odometric signal of the vehicle; check with your installer.

10.0 - PAIRING OF CONTROL UNITS WITH DISPLAY
!
.
.
When the letters “LE” and the upward arrow icon light up on the display, the front control unit has
been paired
Engage reverse gear and wait until the downward arrow icon lights up; this will indicate the rear
control unit has been paired.
The pairing procedure is completed; parameters can eventually be modifed according to individual
needs
!
!
When pairing, make sure reverse gear is disengaged and no similar control units are
activated in the surroundings.
Once the front control unit is powered, you will have one minute to pair it to the display
If one minute has lapsed, you will have to restart the pairing procedure (disconnect and
reconnect the front control unit).

If the display shows “E1” it means that there are other activated control units in the
surroundings; move the vehicle or turn off the other control units.
