1. SAFETY INSTRUCTIONS
Risk of injury
f We would like to point out that an excess of high
volumes and long periods of listening may cause
hearing damage. Hearing defects always constitute
an irreversible impairment of hearing ability.
f If you suffer from tinnitus, do not use headphones,
or reduce the volume.
f According to regulations to protect employees
against damages caused by noise and vibrations,
please follow these instructions:
f When connecting the headphones, please ensure
that the volume is turned down to minimum. Adjust
the volume after putting on the headphones.
Danger to life
f Headphones drastically reduce perception of exter-
nal sounds. Using headphones in road traffic can be
potentially dangerous. The user's hearing must not
be impaired to the extent that it causes road safety
risks. Please also make sure that you do not use the
headphones in traffic as well as within an area of
potentially dangerous machines and tools.
f Furthermore, avoid using the headphones in
situations where hearing must not be affected,
especially when crossing a railway crossing or at a
construction site.
