7 General information about radio
operation
Radio transmission is performed on a non-exclusive trans-
mission path, which means that there is a possibility of
interference occurring. Interference can be caused by e.g.
switching operations, electrical motors or defective electri-
cal 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.
Hereby, eQ-3 Entwicklung GmbH declares that this device
conforms with the essential requirements and other rel-
evant regulations of Directive 1999/5/EC.
