3.5 EU conformity declaration
Please see the EU declaration of conformity post-
ed at www.janitza.de for the laws, standards and
directives applied by Janitza electronics GmbH for
the devices. The CE conformity marking require-
ments for the device arise from the EU conformity
declaration and the laws, standards and directives
mentioned therein.
3.6 FCC Declaration of Conformity
The device:
· complies with Part 15 of the FCC Rules for Class
B digital devices (limits to protect against harmful
interference in a residential installation).
· generates, uses and can radiate high-frequency
energy
· can cause harmful interference to radio commu-
nications if not installed and used properly. There
is no guarantee that interference will not occur in
a particular installation.
If there is radio or television reception interference,
which can be determined by turning the device on
and off, proceed as follows:
· Align or reposition the receiving antenna.
· Increase the distance between the device and the
radio/television receiver.
· Connect the device and the radio/television
receiver in different circuits.
· if necessary, contact Janitza support or a radio/
television technician.
