Inserting and removing the instrument
(ThinTube)
Inserting the instrument
• Hang the instrument over the top
of the ear.
• Grasp the sound tube where
it bends. The dome should be
placed far enough into the ear that
the sound tube lies flush with your
head. When the dome is placed
appropriately, you should not see
the sound tube sticking out when
you look directly into a mirror.
• If the device whistles, the most
likely reason is that the dome is not
placed correctly in the ear canal.
Other reasons can be buildup of
earwax in the ear canal, or that
the sound tube connection to the
instrument has become loose, in
which case the sound tube must
be changed. It is also possible that
the instrument settings are not
optimal. If you have ruled out other
reasons for the instrument squea-
ling, it is recommended to contact
your hearing care professional.
