Safety Precautions
Please ensure that the product is properly used by observing the warnings and cautions below to prevent any risk
and/or damage to property.
Product Storage and Management
• Keep the product free of dust. It may damage mechanical and electronic parts of the product.
• Do not store the product in high temperatures as this may reduce the life span of electronic devices, damage the
battery, and/or melt plastic parts of the product.
• Excessive heat (e.g. exhaust heat) can cause damage to the decoration, the inner shell of the helmet and the
interior lining.
• Do not store the product in cold temperatures. Abrupt changes in temperatures may cause condensation and
damage electronic circuits.
• Do not clean the product with cleaning solvents, toxic chemicals, or strong detergents as this may damage the
product.
• Direct contact with motor fuel, thinners or solvents can destroy the structure of the inner and outer shell. Make sure
the helmet does not come into contact with such substances, even for cleaning purposes.
• Do not paint the product. Paint may obstruct moving parts or interfere with the normal operation of the product.
• Do not drop or otherwise shock the product. It may damage the product or its internal electronic circuits.
• Do not disassemble, repair or modify the product as this may damage the product and invalidate the product
warranty.
• Do not store the product in humid environments, especially for long time storage.
• The helmet should be replaced after 5 to 7 years, depending on use and care. Although the outer shell is in principle
capable of a longer service life, the occurrence of material fatigue and wear to other components, as well as the
overall action of the helmet and the unknown conditions in which the helmet has been used, make it advisable for
your own safety to replace the helmet after this period of use.
• Original components (in particular on the outer shell, inner shell and restraint system) should not be altered or
removed. The fitting of additional parts from other manufacturers that have not been recommended can reduce the
protective effect and renders the DOT certification and all warranty and insurance claims invalid.
• Use only original parts, replacement parts and accessories that Sena has expressly approved for your helmet.
Product Use
• Motorcycling is associated with particular risks and dangers for the rider and passenger. These risks and dangers
can be reduced, but not eliminated completely, by wearing a helmet. It is impossible to state precisely what the
protective effect of a helmet will be in the event of an accident. Safe riding techniques, adapted to the particular road
and weather conditions, are essential for your safety.
• To provide adequate protection, the helmet must fit well and be securely fastened.
• Always fasten the chinstrap before setting off and check that the fastening system and strap are correctly in
position.
• Never ride with the chinstrap unfastened or incorrectly adjusted. The chinstrap must be correctly
positioned and must not come loose when pulled. The fastener is not correctly closed if the chinstrap becomes loose
when pulled.
• The full protective function of a helmet can no longer be guaranteed after an accident or impact. Like the crumple
zone of a car, the impact energy of a collision is absorbed by complete or partial destruction of the structure of the
outer and/or inner shell of the helmet. Because of the way helmets are designed, this damage is rarely visible from
the outside. The safety helmet is designed to absorb only one impact. It is therefore essential to replace the helmet
after a fall, accident or other violent impact. For safety reasons, the old helmet should be rendered unusable.
• The helmet safety mechanism described above can also cause small cracks in the shell when the helmet is dropped
from a small height (less than 1 meter).
• Any helmet that has been subjected to a violent impact should be replaced.
• No helmet provides absolute protection from all conceivable impacts. This helmet has been specially developed for
motorcycle riding and is unsuitable for other purposes.
• Examine the helmet for damage at regular intervals. Small scratches will not impair the protective function of your
helmet.
• In some regions, it is prohibited by law to ride motorcycles while wearing headsets. Therefore be
certain to comply with all relevant laws in the region before using the product.
• Use of the product at a high volume for a long period of time may damage your eardrums or hearing ability. Keep
the volume at a modest level to prevent damage.
• Do not cause impact to the product or touch it with sharp tools as this may damage the product.
• Do not use the product in high-temperatures or apply heat to the product as this may cause damage, explosion, or
fire.
• Keep product away from pets or small children. It may damage the product.
• In any place where wireless communication is prohibited, such as hospitals or airplanes, turn off the power and
refrain from using the product. In a place where wireless communication is prohibited, electromagnetic waves may
cause hazards or accidents.
• Do not use the product near hazardous explosives. When it is near any explosion hazards, turn off the power and
heed any regulations, instructions, and signs in the area.
Battery
This product has an irreplaceable rechargeable battery inside. Therefore, when using the product, make sure to
adhere to the following:
• Never separate the battery from the product as this may damage the product.
• The battery performance may be reduced over time with usage.
• In recharging the battery, make sure to use an approved charger provided by the manufacturer. Use of a non-
approved charger may cause fire, explosion, leakage, and other hazards may also reduce the life time or
performance of the battery.
• Any 3rd party USB charger can be used with Sena products if the charger is approved by either the FCC, CE, IC or
other locally approved agencies that Sena accepts.
• Store the battery at temperatures of 15°C~25°C (59°F~77°F). Higher or lower temperatures may
reduce the capacity and life of the battery, or may cause temporary non-operation. Do not use the
product in sub-zero temperature, because it may cause serious reduction of the battery performance.
• If you apply heat to the battery or throw it into a fire, it may explode.
• Do not use the product with a damaged battery. It may explode and/ or cause accidents.
