Guidance and manufacturer's declaration - electromagnetic immunity
The [BPW-1005] is intended for use in the electromagnetic environment specified below.
The customer or the user of the [BPW-1005] should assure that it is used in such an environment.
IEC 60601
Immunity test
test level
Radiated RF 3 V/m 80 MHz to
IEC 61000-4-3 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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
a
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 [BPW-1005] is used exceeds
the applicable RF compliance level above, the [BPW-1005] should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
[BPW-1005].
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
b
Compliance
level
Portable and mobile RF communications equipment
should be used no closer to any part of the
BPW-1005, 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 = 2.3 √
3 V/m
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,
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of equipment
marked with the following symbol:
