Turn ignition on and wait 20 seconds.  The dashboard LED illuminates and remains
on about 3 seconds.
Before the dashboard LED extinguishes, turn ignition off and then on again.  A short
and sharp sound signal confirms that the system is ready for pairing. The LED switches
off. You have 6 seconds to complete the operation as described below.
Press push-button n. 1 of a transmitter (or press both transmitters in turn, if you want to
pair two). The LED illuminates shortly, to confirm that pairing has been successful.
Once the operation is completed, turn the ignition off. If the ignition remains on, the
system will automatically quit the pairing procedure In both cases the exit from the
procedure is confirmed by a short sharp audible signal.
Important:
1) For security reasons, each system can accept a maximum of two remote
transmitters.
2) Every pairing procedure disables the transmitters which the receiver had previously
been paired with. Therefore: if you have lost a transmitter and you wish to pair a
spare one, do not forget that the one which has remained in your possession has to
be re-paired too (or it will stop working). If you are not able to acquire a replacement
transmitter quickly, then simply repeat the process to re-pair your existing
transmitter, and this will disable the missing transmitter.
