Guidance and manufacturer’s declaration-electromagnetic immunity
The Ear Thermometer is intended for use in the electromagnetic environment specified below.
The customer or the user of the Ear 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 Ear Thermometer, including cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance.
d=1.2
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 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 Ear Thermometer is used exceeds
the applicable RF compliance level above, the Ear Thermometer should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Ear
Thermometer. Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.
