Guidance and declaration of manufacturer-electromagnetic immunity
The SFT53 Ear Thermometer is intended for use in the electromagnetic environment specified below.
The customer or the user of the SFT53 Ear Thermometer should assure that it is used in such an environment.
IMMUNITY IEC 60601
test test level
Conducted RF 3Vrms
IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3 V/m
IEC 61000- 4-3 80 MHz to
2.5 GHz
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.
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
SFT53 Multi-function Thermometer is used exceeds the applicable RF compliance level above, the SFT53 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 SFT53 Multi-function Thermometer.
Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any part of the
SFT53 Ear Thermometer, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:

Where P is the maximum output power rating of the transmitter in watts (W) according to the trans-
mitter manufacturer and d is the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
be less than the compliance level in each frequency range.
