Phonak Terra User Manual page 37

Portable RF communications equipment (including peripherals
such as antenna cables and external antennas) should be used
no closer than 30 cm (12 inches) to any part of the hearing
aids, including cables speci ed by the manufacturer.
Otherwise, degradation of the performance of this equipment
could result.
Avoid strong physical impacts to the ear when wearing
a hearing aid with customized earpiece. The stability of
customized earpieces is designed for normal use. A strong
physical impact to the ear (e.g. during sports) may cause the
customized earpiece to break. This may lead to perforation
of the ear canal or eardrum.
After mechanical stress or shock to the hearing aid, please
ensure the hearing aid shell is intact before placing it in the
ear.
Use of this equipment adjacent to or stacked with other
equipment should be avoided because it could result in
improper operation. If such use is necessary, this equipment
and the other equipment should be observed to verify that
they are operating normally.

The majority of hearing aid users have a hearing loss for which
a deterioration in hearing is not to be expected with regular
use of a hearing aid in everyday situations. Only a small group
of hearing aid wearers with hearing loss, may be at risk of
deterioration in hearing after a long period of use.
Hearing aids should not be tted with domes / wax protection
systems when used by patients with perforated eardrums,
in amed ear canals or otherwise exposed middle ear cavities.
In these cases, we recommend the use of a classic earmold. In
the unlikely case that any part of this product should remain
in the ear canal, it is strongly recommended to see a physician
for safe removal.
In very rare cases if not securely attached, a dome or cerumen
stop can remain in your ear canal when removing the hearing
aid from the ear. In the unlikely case that such part gets stuck
in your ear canal, it is strongly recommended to see a
physician for safe removal.
