Important safety instructions
Hazard warnings on the rear of the receiver
The label shown on the left is attached to the rear of the receiver.
The symbols on this label have the following meaning:
This symbol is intended to alert the user to the presence of uninsulated
dangerous voltage within the receiver’s enclosure that may be of sufficient
magnitude to constitute risk of fire or electric shock.
This symbol is intended to alert the user to the risk of electric shock if the
receiver is opened. There are no user serviceable parts inside. Refer
servicing to qualified personnel only.
This symbol indicates the presence of important operating and mainte-
nance instructions in the literature accompanying this receiver.
Overloading
Do not overload wall outlets and extension cords 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 exceeding 85 dB(A).
85 dB(A) is the sound pressure corresponding to the maximum permis-
sible 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 dura-
tions 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.
