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