The rechargeable hearing aids contain lithium-ion batteries
and the charger contains a lithium-polymer battery that can
be taken onto airplanes as carry-on luggage. The charger
cannot be placed in the checked-in baggage and can only be
placed in the carry-on luggage.
Your hearing aids operate between 2.4 GHz -2.48 GHz
frequency range. When flying please check if
flight operator requires devices to be switched
into flight mode, see chapter 14.
The hearing aids (specially programmed for each hearing loss)
must only be used by the intended person. They should not be
used by any other person as they could damage hearing.
Changes or modifications to the hearing aid that were not
explicitly approved by Sonova AG are not permitted. Such
changes may damage your ear or the hearing aid.
