Safety instructions
Never open an electronic unit! If units are opened by
customers in breach of this instruction, the warranty
becomes null and void.
Use the unit in dry rooms only.
Use a damp cloth for cleaning the unit. Do not use any
cleansing agents or solvents.
Attention! High Volume!
This is a professional transmission
system. Commercial use is subject to the
rules and regulations of the trade
association responsible. Sennheiser, as
the manufacturer, is therefore obliged to expressly point
out possible health risk s arising from use.
This system is capable of producing sound pressure
exceeding 85 dB(A). 85 dB(A) is the sound pressure
corresponding to the maximum permissible volume which
is by law (in some countries) allowed to affect your hearing
for the duration of a working day. It is used as a basis
according to the specifications of industrial medicine.
Higher volumes or longer durations can damage your
hearing. At higher volumes, the duration must be
shortened in order to prevent damage. The following are
sure signs that you have been subjected to excessive noise
for too long a time:
y You can hear ringing or whistling sounds in your ears.
y You have the impression (even for a short time only) that
you can no longer hear high notes.
