Manufacturer’s declaration-electromagnetic immunity

The B200 is intended for use in the electromagnetic environment specified below. 
The customer or the user of the B200 should assure that is used in such and environment.

Immunity test

IEC 60601 test level

Compliance level

Electromagnetic environment - guidance

Conducted RF
IEC 61000-4-6

3 Vrms:
0,15 MHz – 80 MHz
6 Vrms: 
in ISM and amateur
radio bands between
0,15 MHz and 80 MHz 

3 Vrms:
0,15 MHz – 80 MHz
6 Vrms: 
in ISM and amateur
radio bands between
0,15 MHz and 80 MHz

Portable and mobile RF communications equipment should be used no closer 

to any part of the B200 including cables, 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 to 800 MHz

d = 2,3 √P 800MHz to 2,7 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:

Radiated RF
IEC 61000-4-3

80 % AM at 1 kHz e)  
10 V/m
80 MHz – 2,7 GHz b)
80 % AM at 1 kHz c)

80 % AM at 1 kHz e) 
10 V/m
80 MHz – 2,7 GHz 
80 % AM at 1 kHz

NOTE1   At 80 MHz and 800 MHz, the higher frequency range applies.

NOTE2  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 beconsidered. If the measured field strength in the location in which the B200 is used exceeds the applicable RF compliance 

level above, the B200 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as 

re-orienting or relocating the B200.

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