Cleaning the sound tube and dome
The ThinTube
The ThinTube feeds the amplified sound from the hearing instru-
ment into the ear. It is important that the ThinTube and the dome fit
correctly into your ear. If the ThinTube or the dome irritate your ear
in any way and prevent you from wearing your hearing instrument,
please contact your hearing care professional. You should never
attempt to modify the shape of the ThinTube yourself.
The ThinTube and the dome should
be cleaned regularly. Remove the
ThinTube from the instrument before
cleaning by unscrewing it. Use a
damp cloth to clean the ThinTube
and dome on the outside and use
the black cleaning rod to “push” any
debris out of the sound tube. The
cleaning rod should be inserted
where the ThinTube attaches to the
instrument and pushed all the way through the ThinTube and out
through the dome. It is not recommended to submerge or rinse the
ThinTube and dome with water, as there is a risk that a water drop
may become lodged in the ThinTube. If this should occur, it will
prevent sound coming through the ThinTube, and may be harmful
for the instrument’s electronics.
The ThinTube and dome should be changed every third month or
sooner if the ThinTube becomes stiff or brittle. We recommend that
you have your hearing care professional change the dome for you.
If your hearing care professional instructs you to change the domes
yourself, make sure that they are securely fastened to the ThinTube
before inserting them in your ear. A failure to change the domes in
accordance with the instructions could result in injury.
