Table 4
Recommended separation distances between portable and mobile RF communications equipment and the EQUIPMENT or
SYSTEM-for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the SFT65 Multi-function
Thermometer
The SFT65
Multi-function
Thermometer is intended for use in an electromagnetic environment in which radiated RF distances are con-
trolled. The customer or the user of the T SFT65
Multi-function
Thermometer can help prevent electromagnetic interference by maintai-
ning a minimum distance between portable and mobile RF communications equipment (transmitters) and the SFT65
Multi-function
Thermometer as recommended below according to the maximum output power of the communications equipment.

80 MHz to 800 MHz
d = 1.2
800 MHz to 2.5 GHz
d = 2.3

1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
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 trans
-
mitter 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 aected by absorption and reflection from
structures, objects and people.
