Important safety instructions www Hazard warnings on the rear of the ADN CU1 central unit/ADN PS power supply The label shown on the left is attached to the rear of the ADN CU1 central unit/ ADN PS power supply. The symbols on this label have the following meaning: Presence of uninsulated dangerous voltage within the ADN CU1 central unit's/ ADN PS power supply's enclosure that may be of sufficient magnitude to constitute risk of fire or electric shock. Never open the ADN CU1 central unit/ADN PS power supply as there is a risk of electric shock. There are no user serviceable parts inside. Refer servicing to an 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 These products are used for commercial purposes. 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. 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. Intended use Intended use of the products includes • using the products for professional purposes, • having read and understood this instruction manual, especially the chapter "Important safety instructions" on page 3, • using the products within the operating conditions and limitations described in this instruction manual. "Improper use" means using the products other than as described in this instruction manual, or under operating conditions which differ from those described herein.
