Recommended separation distances between portable and mobile RF communications equipment and the FT78 Ear thermometer
The FT78 Ear thermometer is intended for use in an electromagnetic environment in which radiated RF distances are controlled. The custo-
mer or the user of the T FT78 Ear thermometer can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the FT78 Ear 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 distanced 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) according 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 struc-
tures, objects and people.
