3.13 FCC Declaration of Conformity
The device:
·complies with Part 15 of the FCC Rules for Class
B digital devices (limits to protect against harm-
ful 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.
