Important safety instructions
Hazard warnings on the rear of the receiver
The label shown on the left is attached to the rear of the EM 9046.
The symbols on this label have the following meaning:
Presence of uninsulated dangerous voltage within the EM 9046’s enclo-
sure that may be of sufficient magnitude to constitute a risk of electric
shock.
Never open the EM 9046 as there is a risk of electric shock. There are no
user serviceable parts inside. Never attempt to change the modules of the
EM 9046 yourself. Always refer repairs, servicing and the change of the
modules to your authorized Sennheiser service partner.
Read and follow the safety and operating instructions contained in the
instruction manual.
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
This is a professional receiver. Commercial use is subject to the rules and
regulations of the trade association responsible. Sennheiser, as the manu-
facturer, is therefore obliged to expressly point out possible health risks
arising from use.
This receiver 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 accord-
ing 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.
