FCC Interference Statement (Part 15.105 (b))
(USA only)
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This equipment
generates uses and can radiate radio frequency energy
and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications. However, there is no guarantee that
interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio
or television reception, which can be determined by
turning the equipment off and on, the user is encouraged
to try to correct the interference by one of the following
measures:

Thermostats
To comply with FCC and Industry Canada RF exposure
limits for general population/ uncontrolled exposure, the
antenna(s) used for these transmitters must be installed
to provide a separation distance of at least 20 cm from
all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.

RSS-GEN
Under Industry Canada regulations, this radio transmitter
may only operate using an antenna of type and
maximum (or lesser) gain approved for the transmitter by
Industry Canada. To reduce potential radio interference
to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated
power (e.i.r.p.) is not more than that necessary for
successful communication.
