Recommended separation distances between portable and mobile RF communications equipment and the SFT77 Multi-function
Thermometer
The SFT77 Multi-function Thermometer is intended for use in an electromagnetic environment in which radiated RF distances are control-
led. The customer or the user of the SFT77 Multi-function Thermometer can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the SFT77 Multi-function Thermome-
ter 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 esti-
mated 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 8- 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.
