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.
