9 General information about radio
operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possi-
bility of interference occurring. Interference can also
be caused by switching operations, electrical motors
or defective electrical devices.
The range of transmission within buildings can
dier greatly from that available in the open air.
Besides the transmitting power and the recep-
tion characteristics of the receiver, environ-
mental 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
HomematicIP HMIP-HAP is in compliance with Directive
2014/53/EU. The full text of the EU declaration of
conformity is available at the following internet address:

8 Maintenance and cleaning
The device does not require you to carry out
any maintenance. Enlist the help of an expert to
carry out any maintenance or repairs.
Clean the device using a soft, lint-free cloth that is
clean and dry. You may dampen the cloth a little with
lukewarm water in order to remove more stubborn
marks. Do not use any detergents containing solvents,
as they could corrode the plastic housing and label.
