Closed domes:
The closed dome has a different design than the open
dome, refer to picture (page 14). 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.
