Guidance and manufacturer's declaration - electromagnetic immunity
The BP4GAPO-2M is intended for use in the electromagnetic environment specified below. The customer or the user of the BP4GAPO-2M should assure that
it is used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment-guidance
Conducted RF 3 Vrms
IEC 61000-4-6 150 KHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80MHz 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
broad-cast 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 BP4GAPO-2M is used exceeds the applicable RF compliance level
above, the BP4GAPO-2M should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the BP4GAPO-2M.
b
Over the frequency range 150 kHz to 80 MHz, field strenghts should be less than 3 V/m.
Not applicable Portable and mobile RF communications equipment should be used no closer to any part of the
BP4GAPO-2M including cables, than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
3 V/m Recommended separation distance:
d = 1,2 √
P
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,

Interference may occur in the vicinity of equipment marked with the following symbol:
d = 1,2 √ 80MHz to 800 MHz
P
should be less than the compliance level in each frequency range.
d = 2,3 √ 800MHz to 2,5 GHz
