Recommended separation distances between portable and
mobile RF communications equipment and Infra-red Forehe-
ad Thermometer
Infra-red Forehead Thermometer is intended for use in an
electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of Infra-red
Forehead Thermometer can help prevent electromagnetic in-
terference by maintaining a minimum distance between por-
table and mobile RF communications equipment (transmit-
ters) and Infra-red Forehead Thermometer as recommended
below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not
listed above the recommended separation distance d in
meters (m) can be estimated using the equation applicable
to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) accor-
ding to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for
the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
For any question, please contact us, CA-MI Srl,
first, we will sort the problem for you, please refer
