Guidance and manufacture’s declaration – electromagnetic immunity
Immunity test IEC 60601 test level
Not applicable
Compliance level Electromagnetic environment - guidance
The Non Contact Infrared Body Thermometer is intended for use in the electromagnetic environment
speci�ied below. The customer or the user ofthe Non Contact Infrared Body Thermometer should assure that
it is used in such an environment.
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz
10 V/m
Radiated RF
IEC 61000-4-3
10V/m
80 MHz to 2.5 GHz
Portable and mobile RF communications equipment
should be used no closer to any part of the Non
Contact Infrared Body Thermometer, including
cables, than the recommended separation distance
calculated from 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 and d is the recommended separation
distance in metres (m).
Field strengths from �ixed RF transmitters, as
determined by an electromagnetic site survey,a should
be less than the compliance level in each frequency
range.b
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 affected by absorption
and re�lection from structures, objects and people.
a Field strengths from �ixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to �ixed RF transmitters, an electromagnetic site survey
should be considered. If the measured �ield strength in the location in which the Non Contact Infrared Body
Thermometer is used exceeds the applicable RF compliance level above, the Non Contact Infrared Body
Thermometer should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Non Contact Infrared Body Thermometer.
b Over the frequency range 150 kHz to 80 MHz, �ield strengths should be less than 10 V/m.
