Guidance and manufacturer’s declaration – electromagnetic immunity

The SFT65 Multi-function Thermometer is intended for use in the electromagnetic environment speciﬁed below. The customer or the

user of the SFT65 Multi-function Thermometer should assure that it is used in such an environment.

Portable and mobile RF communications equipment should be used no closer to any

part of the SFT65 Multi-function Thermometer, including cables, than the recommen

ded separation distance calculated from the equation applicable to the frequency of the

transmitter.

Recommended separation distance:

d = 1.2

80 MHz to 800 MHz

d = 2.3

800 MHz to 2.5 GHz

Where P is the maximum output power rating of the transmitter in watts (W) according to

the transmitter manufacturer and d is the recommended separation distance in meters

(m).

Field strengths from ﬁxed RF transmitters, as determined by an electromagnetic site

survey,

should be less than the compliance level in each frequency range.

Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, 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.

Field strengths from ﬁxed transmitters, such as base stations from radio (cellular/cordless) telephones and land mobile radios, ama

teur radio, AM and FM radio broadcast and TV broadcast can not be predicted theoretic call with accuracy. To assess the electroma-

gnetic environment due to ﬁxed RF transmitters, an electromagnetic site survey should be considered. If the measured ﬁeld strength

in the location in which the SFT65 Multi-function Thermometer is used exceeds the applicable RF compliance level above, the

SFT65 Multi-function Thermometer should be observed to verify normal operation. If abnormal performance is observed, additional

measures may be necessary, such as reorienting or relocating the SFT65 Multi-function Thermometer.

Over the frequency range 150kHz to 80MHz, ﬁeld strengths should be less than [V1] V/m.
