12. Information about radio operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possibility
of interference occurring. Interference can also be caused
by switching operations, electrical motors or defective
electrical devices.
The range of transmission within buildings can differ greatly
from that available in the open air. Besides the transmitting
power and the reception characteristics of the receiver,
environmental factors such as humidity in the vicinity
have an important role to play, as do on-site structural/
screening conditions.
eQ-3 Entwicklung GmbH hereby declares that this device
complies with the essential requirements and other relevant
regulations of Directive 1999/5/EC. You can find the full
declaration of conformity at www.eQ-3.de.
