Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The CEFAR BASIC Electrotherapy System is intended for use in the electromagnetic environment deified below. The customer or
the user of the CEFAR BASIC Electrotherapy System should assure that it is used in such an environment.
IEC 60601
Immunity Test
Test Level
Conducted RF 3 Vrms
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.
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 CEFAR BASIC Electrotherapy System is used exceeds the applicable RF
compliance level above, the CEFAR BASIC Electrotherapy System should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the CEFAR BASIC
Electrotherapy System .
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V 1 ] V/m.
Compliance Level
Portable and mobile RF communications
equipment should be used no closer to any part of the
CEFAR BASIC Electrotherapy System, including cables,
than the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d =
[
[V 1 ] V, where V 1 = 3V
d =
[
[E 1 ] V/m, where E 1 = 3V/m
d =
[
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 fixed 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
