Hearing systems batteries are toxic when
swallowed!
Keep them out of reach of children
and pets. If batteries are swallowed, please
seek the advice of a medical practitioner!
Use only hearing systems that have been specially
programmed for you by a hearing care professional.
Other instruments may be ineffective and may, in
certain cases, even damage your hearing.
X-ray radiation (e.g. CT scans, MRI scans) may
adversely affect the correct functioning of your
hearing system.
We recommend that you remove
them before undergoing X-ray procedures and keep
them outside the room.
Hearing systems in directional microphone
mode mainly reduce background sounds.
Warning signals coming from behind and vehicles
horns approaching from behind are partially or
completely suppressed.
