Safety check
Upon completion of any service or repairs to this device, ask the service technician to perform
safety checks to determine that the device is in safe operating order.
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 manufacturer, 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 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 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.
