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

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.

paragraph “Exclusions and limitations of the Coverage”.
19.2. Exclusions and limitations of the coverage
This warranty only covers defects in materials and manufacturing. Nolangroup shall not be considered responsible
for product defects that can be attributed, either partially or in full, to any other cause, including but not limited to:
Defects or damages resulting from using the Product in conditions that differ from the usual ones.

Moreover, the warranty does not cover product defects caused by fortuitous events, modifications or
adjustments, causes of force majeur or damages deriving from the product coming in contact with liquids.
The internal helmet components are not and cannot be waterproof. Consequently, any improper exposure to
rain, humidity, food spillages or other liquids can result in damages to the N-Com electronic devices, damages
for which Nolangroup shall not be responsible.
This warranty does not include those parts subject to wear and tear such as, for example, the rechargeable
battery and the cables used for connection between the various N-Com systems or between the N-Com
systems and other devices.
Since Nolangroup does not supply the system on which the cell phones work, it shall not be responsible for
the operation, availability, coverage, services or range pertaining to the aforementioned system.
Whenever the product is used in conjunction with accessories or equipment not supplied by Nolangroup,

ENCLOSED WITH THE PRODUCT.
AFTER 2 (TWO) YEARS FROM THE DATE OF PURCHASE, THIS LIMITED WARRANTY IS VOID FOR ALL EFFECTS AND
PURPOSES.
Repairs or maintenance under warranty do not extend the period of the warranty itself. Therefore, in case the
product or one of its components is replaced, this does not initiate a new warranty period, as the purchase date of
the original product shall be taken into account for warranty purposes.
Only for repairs or replacement of electronic components, in the event that Nolangroup proceeds to repairing or
replacing the product, said product shall enjoy a warranty period equal to the residual portion of the original

LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES INCLUDING BUT NOT LIMITED TO LOST PROFITS OR
COMMERCIAL DAMAGES, TO THE FULL EXTENT THOSE DAMAGES CAN BE DISCLAIMED BY THE LAW.
NOLANGROUP RESERVES ITSELF THE RIGHT TO MODIFY, AT ANY TIME AND WITHOUT ADVANCE NOTICE, THE
PRODUCT CHARACTERISTICS, FUNCTIONS, COMPATIBILITY AND SOFTWARE.

the duration of implied warranties; as a result of this, the previous limitations and exclusions may not be applicable
to you.

the consumer’s rights towards the dealer sanctioned by the purchase/sale contract.
This warranty is valid throughout the European territory, and it represents the only express warranty provided by
Nolangroup in relation to the sale of its own products. This warranty does not affect the rights to which the buyer is
entitled and which are expressly provided for by Directive 1999/44/CE.
