AQUAPHON system
2.1
General information about the system
2.1.1
Communication
The components of the
AQUAPHON
system communicate by
bidirectional SDR (SDR: Sewerin Digital Radio). Wireless com-
munication allows the user considerable freedom of movement.
The sound quality of the acoustic playback is not affected by
swinging cables.
2.1.2
Hearing protection
The
AQUAPHON
system protects the user's hearing against
sudden, loud interference noise. This type of interference noise
can occur, for example, when vehicles drive by or when the user
with a touch microphone slips off the contact point.
The hearing protection function activates when the individu-
al hearing protection threshold setting is exceeded. When the
noise from the source of interference ceases, hearing protection
switches off again automatically.
The way the hearing protection works depends on the settings

Note:
Another way of protecting the hearing from loud noises is to set
the volume only as high as is absolutely necessary.
