 the headset is not placed close to magnetic fields (for
example, loudspeakers).

has been exposed to large temperature fluctuations,
wait approximately two hours until the headset has
reached ambient temperature before starting it up.
 the headset is not exposed to excessive shocks and
vibrations
 always lay connected cables in such a way that
