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.
