2.3 Universal three level ear plug
The ear plug is used for adaptation of the ear microphone / earphone to the auditory canal. It is
»pushed« with a rotating motion onto the ear microphone / earphone (Fig. 6). If no perfect seat in the
ear is achievable, because the standard ear plug is too large, the largest lamella ring can be cut off with
a sharp knife (figure 7-9).

2.4 Individually ear mould
This ear mould (example Fig. 10) ensures maximum wear comfort and transmission quality. Only when
carry the individually ear moulds the highest possible protection of the ears is ensured. It is moulded
according to an individual impression of the auditory canal either for wearing in the right ear or in the left
ear. For different personal needs different variants are available. The earphone is “clipped” in the ear
mould. The ear mould is worn in the ear.
