Conference call function

B4 allows a conference call with Rider and Pillion Passenger.

When a call comes in on a mobile phone connected via Bluetooth to B4, the Rider-

Pillion Passenger intercom is temporarily turned off. However, if you wish to share the

phone call with the other helmet, simply turn on the intercom manually during the

phone call (by briefly pressing “on”).

Note: this functionality is possible only if the passenger is provided with a Bluetooth

Kit3 system (or N-Com B4 system)

8. GPS SATELLITE NAVIGATOR FUNCTIONS

B4 is compatible with the most common satellite navigators for motorcycles.

By connecting the N-Com system to the GPS, all instructions will be transferred to the

helmet.

Every time the navigator communicates instructions, the intercom via Bluetooth with

the Pillion Passenger is cut off and automatically restored at the end of the

communication.

Note: If the navigator is pre-set for connection to a Bluetooth mobile phone, you will

be able to receive the phone call audio directly in the helmet through the GPS. In

this case, you can answer the call directly from the navigator.

GPS Conference Call Function

The Conference function allows you to keep the “Rider-Pillion Passenger” intercom

open even while the satellite navigator is giving instructions, thus preventing the

intercom mode to be turned off every time the navigator gives instructions.
