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.
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.
Hereby, eQ-3 AG, Maiburger Str. 29, 26789 Leer/Germany declares
that the radio equipment type Homematic IP HmIP-eTRV-B-2 is
in compliance with Directive 2014/53/EU. The full text of the EU
declaration of conformity is available at the following internet address:
