Inserting and removing the instrument
(with FlexTubeThin Tube)
Inserting the instrument
• Hang the instrument over the
top of the ear.
• Grasp theFlexTube/Thin Tube
where it bends and push
the dome into your ear
canal. The dome should
be placed far enough into
the ear that the sound tube
lies ush with your head.
When the dome is placed
appropriately, you should not
see the FlexTube/Thin 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 con-
nection 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 squealing, it is
recommended to ontact your hearing care professional.
