Preparation
Closed domes
The closed dome has a different design than the open
dome, refer to picture. The closed dome consists of two
fins overlapping each other. Before inserting the closed
dome into the ear canal it is important to check the
position of these fins. The bigger fin must be positioned
over the smaller fin, see picture
햵
. If the position
is incorrect
햶
, you can easily adjust it with one finger,
just bend smoothly the bigger fin forwards and then
back again so that it is overlapping the smaller one, see
picture
햷
. Make also sure that the slit of the closed
dome is in a horizontal position on the tube unit,
as shown in picture
햵
. Your closed dome and external
receiver unit is ready to be inserted into the ear, refer
to page 20.
