Important safety instructions
Risk of fire due to overloading
Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Danger of hearing damage due to high volumes
These products are used for commercial purposes. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the man- ufacturer, is therefore obliged to expressly point out possible health risks arising from use.
When the conference participants listen to the floor channel via headphones, they can adjust the volume themselves. In doing so, sound pressure exceeding 85 dB(A) can be produced. 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.
Inform the conference participants about these facts and, if necessary, ask them to set the volume to a medium level.
