er than replacing the battery when necessary. Enlist the help of an
expert to carry out any repairs.

11 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 significantly from
that available in open space. 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-WUA is in compliance with
Directive 2014/53/EU. The full text of the EU declaration of conformity is
