1. WARNINGS AND SAFETY
Read this User Manual carefully, as well as the User Manuals for other N-Com kits that you will be using with the N-
Com B901. Read the simple rules listed below. Failure to comply with these rules may lead to dangerous situations.
Caution: The product cannot be used in official or non-official competitions, motordromes, circuits, racing tracks and
the like.
Caution: Installation of the N-Com B901 system results in a weight increase of approximately 110g, which is added
to the weight of the helmet and of the other accessories.
Warning: The electronic components of the N-Com system mounted inside the helmet are not waterproof.
Consequently, make sure the inside of the helmet, including the comfort padding, does not get wet in order to
avoid damage to the system. If it does, remove the N-Com system and the helmet comfort padding and let it
air dry. Disconnect the battery connector and let it dry as well.
1.1. Road safety
Always obey all Traffic Regulations in force. While riding the motorcycle, your hands should always be engaged in
actually riding the vehicle. Any operation to the N-Com system must be carried out with the vehicle stopped.
Specifically:
Set your cell phone on automatic answer (see the cell phone instructions to do this).
If your cell phone is not equipped with this function, first stop your vehicle in a safe area, in compliance with
Traffic Regulations and then answer the call.
Do not make any calls while riding. Stop your vehicle in a safe place in compliance with Traffic Regulations, and
then make the call.
Adjust the volume so that it does not cause a disturbance or distraction while riding and at the same time allows
you to distinctively hear background noises.
Do not operate your cell phone or other devices connected to N-Com while riding your motorcycle.
In all cases, obey the Traffic Regulations and remember that riding the motorcycle has absolute priority over any
other maneuver.
1.2. Switching on the system in safe environments
When using the N-Com system, comply with all limitations and instructions related to the use of cell phones.
Do not turn on your cell phone or the N-Com system whenever their use is forbidden or when the devices can
cause interference or dangerous situations.
Turn off while refueling. Do not use the N-Com system in filling stations. Do not use the device near combustible
materials or chemical products.
Turn off in proximity to explosive materials.
1.3. Interferences
All phones and devices with wireless signal transmission are subject to interferences that may affect the
performance of the device connected to them. These interferences are not ascribable to a defect of the N-Com
system.
1.4. Appropriate use
Use the device only in the normal position, as described in the product documentation. Do not attempt to
disassemble, tamper with or modify any part of the N-Com system.
Caution: Adjust the volume of the N-Com system (where provided) and of the audio sources connected to it before
you use the system on the road.
Caution: Adjusting the volume to very high levels may cause damage to your hearing.
Caution: Adjust the volume of the N-Com system (where provided) and of the audio sources connected to it so as to
avoid audio reproduction at high volumes. Constant exposure to high audio volumes may damage your
hearing.

Caution: An incorrect installation of the system in the helmet may alter the aerodynamic and safety characteristics of
the helmet itself, thus creating dangerous conditions. Install the N-Com system according to the instructions
provided in the product documentation. In case of doubt, please contact your local N-Com dealer.
Warning: Listening to other equipment should not interfere with driving the vehicle, which must be the top priority
at all times. Carry out all operations on the electronic equipment and on the N-Com system with the vehicle
stopped, in compliance with Traffic Regulations.
Caution: B901 allows radio reception. Any radio licence fees are to the user’s charge.
1.5. Qualified personnel
Only qualified personnel can carry out technical assistance on this product. In case of any malfunction, always
turn to your local dealer.
The helmet is a safety device. Tampering with it and/or with the electronic system inside the helmet, in addition
to invalidating the product warranty, can also lead to dangerous situations.
1.6. Accessories and batteries
Only use the type of batteries, battery chargers and accessories approved by Nolan for the specific model.
The use of a battery type different from the recommended one may lead to dangerous situations and invalidate
the warranty.
Contact your local dealer to see about the availability of approved accessories.
When disconnecting the power supply cable of any accessory or of the battery charger, always grab and pull the
plug not the cable.
Do not use batteries for purposes other than the prescribed ones.
Never use batteries or battery chargers that turn out to be damaged.
Do not short-circuit the battery.
Keep the battery at a temperature between 0° / +45°C (charging); -20° / +60 °C (in use).
Danger of fire or explosion: do not throw the batteries into a fire nor expose them to high temperatures!
Do not throw out batteries together with household refuse. The batteries should be disposed of in compliance
with local regulations
Do not wear the helmet while the battery is recharging.
The helmet should never be left within the reach of unsupervised children in order to prevent damage to their
health caused by access to the batteries.
