Attention! High volume!
This is a professional transmission system.
Commercial use is subject to the safety-at-work
regulations. Sennheiser, as the manufacturer, is
therefore obliged to expressly point out possible
health risks 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.
