Guidance and manufacturer’s declaration – electromagnetic immunity

The device is intended for use in the electromagnetic environments listed below, and should only be used in such environments:

Immunity test

IEC 60601 test level

Compliance level

Electromagnetic environment – guidance

Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3

3 Vrms
150 kHz to 80 MHz
3 V/m
80 MHz to 2.5 GHz

3 Vrms

3 V/m

Portable and mobile RF communications equipment should

be used no closer to any part of the device, 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

80 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 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 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.

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 device

is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance

is observed, additional measures may be necessary, such as reorienting or relocating the device.

b

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
