Important safety instructions

Danger due to high volumes
This is a professional transmitter. 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 risks arising from use.
This transmitter 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 hearing damage. The following are sure signs that you have been subjected
to excessive noise for too long a time:
– You can hear ringing or whistling sounds in your ears.
– You have the impression (even for a short time only) that you can no longer hear high
notes.
