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:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
Thermostats and outdoor sensor
To comply with FCC and Industry Canada RF exposure limits for general population/ uncon-
trolled exposure, the antenna(s) used for these transmitters must be installed to provide a sep-
aration 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.
Remote control
This portable transmitter with its antenna complies with FCC and Industry Canada RF
