Danger due to high volume levels
This product is used for commercial purposes. Commercial use is subject to the rules and reg-
ulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore
obliged to expressly point out possible health risks arising from use.
This product is capable of producing sound pressure levels 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.
Inform all users of these risks and ask them to set the volume to a moderate level if necessary.
Risk of fire due to overloading
Do not overload wall outlets and extension cables as this may result in fire and electric shock.
Safety instructions for antennas
Use safety wires to protect the antennas against tipping/dropping.
The safety wires, rope terminations and coupling links must comply in their dimensioning and
condition with the regulations and standards of the country in which they are used!
