General information about radio
operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possibil-
ity of interference occurring. Interference can also be
caused by switching operations, electrical motors or de-
fective 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.
Hereby, eQ-3 AG, Maiburger Str. 29, 26789 Leer/Germany
declares that the radio equipment type Homematic IP
Doorbell Button is in compliance with Directive
2014/53/EU. The full text of the EU declaration of
conformity is available at the following internet address:
