DANGER! Radio interface
Switch off the headphones in aircraft, hospitals, operating rooms or in the
vicinity of medical electronic systems. The transmitted radio waves can impair
the functionality of sensitive devices. Keep the headphones at least 20cm away
from any pacemakers or implantable cardioverter defibrillators because the
proper functioning of the pacemaker or implantable cardioverter defibrillator
can be impaired by radio waves. The transmitted radio waves can cause
interference in hearing aids. Do not place the device in the vicinity of
flammable gases or in a potentially explosive environment (e.g. paint shop)
when the radio components are switched on because the transmitted radio
waves can cause an explosion or a fire. The range of the radio waves is
dependent on conditions in the surrounding environment. In the event of data
traffic via a wireless connection, it is also possible for unauthorised third parties
to receive data. Targa GmbH is not responsible for radio or television
interference caused by unauthorised changes to this device. In addition, Targa
assumes no responsibility for the replacement or exchange of connecting lines
and devices not indicated by Targa GmbH. The user is solely responsible for
the elimination of interference caused by such unauthorised changes and for
the replacement or exchange of the devices.
DANGER! Risk of explosion!
The headphones must not be thrown into a fire because the built-in battery may
explode.
