Important safety instructions
Hazard warnings on the rear of products with mains plug
The label shown on the left is attached to the rear
of products with mains plug
(ADN CU1 central unit, ADN PS power supplies, ADN-W L10 chargers and ADN-W
CASE UNITS). The symbols on this label have the following meaning:
Presence of uninsulated dangerous voltage within the product’s enclosure
(ADN CU1 central unit, ADN PS power supplies, ADN-W L10 chargers and ADN-W
CASE UNITS) that may be of sufficient magnitude to constitute risk of electric
shock.
Never open the ADN CU1 central unit, the ADN PS power supplies, the ADN-W L10
chargers and the ADN-W CASE UNITS as there is a risk of electric shock. There are
no user serviceable parts inside. Refer servicing to an authorized Sennheiser ser-
vice 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 an
d extension cabl
es as this may result in fire and elec-
tric 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 man-
ufacturer, 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 hear-
ing for the duration of a working day. It is used as a basis according to the specifi-
cations of industrial medicine. Higher volumes or longer durations can damage
your hearing. At higher volumes, the duration must be shortened in order to pre-
vent 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.
Warning on the use of the wireless components
In some countries/regions and for certain ra
di
o channels, the use of wireless com-
ponents is subject to special legal requirements. Only use the wireless components
in accordance with these legal requirements in order to avoid interference to other
radio equipment. Make sure to always set the correct country/region (via the oper-
ating menu of the ADN CU1 central unit) in which the wireless components are to
be used. This ensures that the conference system uses only the radio settings
(radio frequencies and transmission powers) that are approved and legal in the
respective country.
In some countries/regions (e.g. Canada), the use of wireless components operating
in the 5.15 to 5.25 GHz frequency band is restricted to indoor use.
