Closed domes
The closed dome has a different design than the open
dome, refer to picture (page 11). 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 . If the position is incorrect , 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 . Make also
sure that the slit of the closed dome is in a horizontal
position on the tube unit, as shown in picture . Your
closed dome and external receiver unit is ready to be
inserted into the ear, refer to page 11.
