Guidance and manufacturer’s declaration –
electromagnetic immunity
The BPM105/BPM205 is intended for use in the electromagnetic environment specified
below. The customer or the user of the BPM105/BPM205 should assure that it is used in such
an environment.
Electromagnetic environment
–
guidance
Portable and mobile RF communications equipment should be used no closer to any part of
the BPM105/BPM205 , including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter.

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 BPM105/BPM205 is
used exceeds the applicable RF compliance level above, the BPM105/BPM205 should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the BPM105/BPM205.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
