27. Information about radio operation
Radio transmission is performed on a non-exclusive trans-
mission path, which means that there is a possibility of
interference occurring.
Switching operations, electric motors or faulty electric de-
vices are some of the reasons why interference may oc-
cur. The range of transmission within buildings can deviate
greatly from open air distances. Besides the transmitting
power and the reception characteristics of the receiver,
environmental influences such as humidity and local struc-
tures also play an important role.
HUMMEL AG hereby declares that this device conforms
with the essential requirements and other relevant regu-
lations of Directive 1999/5/EC.
