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:

3.2 - AUTOMATIC ACTIVATION OF SENSORS (o )
When ignition is switched ON, the front sensors and the detection system are activated whenever the
speed falls under the preset value (see “Setting of parameters”, parameter 11).
A LED lights up to let you know the sensors are activated and turns off when they are not in operation.
Press the button with the LED to deactivate the sensors (ex. when in queue).
The push-button can be:
Short-pressed (about 1 sec.): to desactivate the sensors until the preselected speed is exceeded.
The sensors will reactivate when the vehicle slows down again to the preselected speed (see
“Parameters”, parameter 11).
Long-pressed (about 5 sec., you will hear a beep): to desactivate the sensors until you turn the
ignition OFF and ON again.
When the speed is higher than the preset value, the front sensors are not in operation and the LED is
off.

2.0 - 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.
The parking system is designed only as a parking aid, it should not be considered to
replace care and attentiveness while manoeuvring.
Detection zones are indicated as “F”.
Detection zones closest to the obstacle are indicated as “FC”.
The STOP zone is the minimum distance detected between an obstacle and the sensor.
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 detection zone.stage-by-stage
For the overall functionality of the parking system, check the programming of the
sensors.

sensors
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 sensors through the push-button, press it at the beginning of the manoeuvre; once you
have parked, press the push-button again to deactivate the sensors.
By modifying the of the front sensors (function 12, preset value “00”), 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 push-
button with the LED. The sensors will automatically deactivate 3” after detecting the last obstacle.

4.1 - LOW POWER SUPPLY SIGNAL
4.2 - FAULTY SENSORS
If, when the control unit is turned on, the battery level is too low to guarantee the accuracy of the
system, the buzzer will almost immediately give out a deep warning tone for 5”.
This will inform the user thatALL the sensors are deactivated.
The driver will therefore know that he will have to do without the parking sensors.
If, when the control unit is turned on, one of the sensors turns out to be inoperative or not connected,an
audio signal will sound for 3”.
If more than one sensor is inoperative, the number of the faulty sensors will be alternatively displayed
on the main control unit.
