sequence listed in the table.
You can display the memory settings of your device (and check the names of the
paired up devices) using the “N-Com Wizard” programme for PC or through the
“App N-Com” for Smartphone Android.
To make it easier to recognize the N-Com systems paired up in “Bike-to-Bike”
mode, you can rename them using the “N-Com Wizard”.
13.2. Making a Bike-to-Bike call
To make a call to another bike that has been previously paired up, go to the Bike-to-Bike menu and
press the button assigned to the helmet to which you want to make the call.
The corresponding tone will be heard in your helmet, after which the call to the selected helmet is
made.
N.B.: In case the memory setting is empty, or the other helmet cannot be reached, an error tone will
sound in your helmet.
13.3. Taking a Bike-to-Bike call
Four calling tones will sound in the helmet receiving the Bike-to-Bike call, and all open audio
functions will be temporarily cut off (including the Rider – Pillion Passenger intercom, if any). The call
can be answered by briefly pressing any key when you hear the ringtone signal.
In case you take the call, communication is automatically established. In case the call is not answered,
the system returns to the situation prior to receiving the call.
N.B.: you can cut off Bike-to-Bike communication from anywhere in the menu by briefly pressing “on”.
Bike-to-Bike intercom communication differs from the Rider-Pillion Passenger kind for certain specific
characteristics:
The audio coming from an external source (connected via cable or Bluetooth) IS NOT shared
with the helmet connected in Bike-to-Bike Intercom mode.
The audio coming from the radio IS NOT shared with the helmet connected in Bike-to-Bike
Intercom mode.
In case the bike-to-bike intercom mode is on and there is no connection with the other Rider
due to out-of-range distances, the two helmets will be automatically reconnected as soon as
the distance is reduced within a range where communication is possible. The search for
automatic reconnection lasts 2 minutes, at the end of which reconnection must be carried out
through the “Bike-to-Bike Call”.
