General information about radio operation

10 General information about radio operation
Radio transmission is performed on a non-exclusive transmission path,
which means that there is a possibility of interference occurring. Inter-
ference can also be caused by switching operations, electrical motors or
defective electrical devices.
The transmission range within buildings can differ greatly from that
available in the open air. Besides the transmitting power and the re-
ception 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 AG, Maiburger Str. 29, 26789 Leer/Germany declares that
the radio equipment type Homematic IP HmIP-WKP is in compliance with
Directive 2014/53/EU. The full text of the EU declaration of conformity is
