Guidance and manufacturer’s declaration-electromagnetic immunity
The Thermometer is intended for use in the electromagnetic environment specified below. The
customer or the user of the Thermometer should assure that it is used in such an environment.
Immunity test
IEC 60601 test level
Compliance level
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3Vrms
150kHz to 80 MHz
Professional healthcare
environment: 3 V/m
Home healthcare environment
10 V/m 80MHz to 2.5 GHz
Not applicable
Professional healthcare
environment: 3 V/m
Home healthcare environment
10 V/m 80MHz - 2700 MHz
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 affected by absorption and
reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations from radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast can not be predicted theoretic call with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the Thermometer is used exceeds the
applicable RF compliance level above, the Thermometer should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Thermometer.
b. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
