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 dier 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
