The fetal heartbeat detector is intended for use in the electromagnetic environments specified below. The
customer or user of the fetal heartbeat detector should ensure that it is used in such an environment.
Immunity test PIEC test level
60601
Radiation 3 V/m
RF 80 MHz a 2,5
IEC GHz
61000-4-3
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guides 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 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 fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the fetal heartbeat
detector is used exceeds the applicable RF compliance level above, the lights should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the fetal heartbeat detector.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance
level
3 V/m Portable and mobile RF communications equipment
should be used no closer to the main unit or any part of the
fetal heartbeat detector than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter. Recommended separation
distance
d = 1,2 √ P
d = 1,2 √ P 80MHz a 800 MHz
d = 1,2 √ P 800MHz a 2.5 GHz
a. where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter ma-
nufacturer 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.
b. Interference may occur near the equipment
marked with the following symbol:
