20.1 Hazard warnings
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 12.
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.
Do not use the hearing aids in explosive areas (mines or
industrial areas with danger of explosions, oxygen rich
environments or areas where flammable anesthetics are
handled).
