Guidance and manufacturer's declaration - electromagnetic immunity
The BM1001 is intended for use in the electromagnetic environment specified below. The customer or the user of the
BM1001 should assure that it is used in such an environment.

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 BM1001 is used exceeds the applicable RF compliance level above, the BM1001 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the BM1001.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the BM1001, including cables,
than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance:
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
a
electromagnetic site survey
, should be less than the compliance
level in each frequency range

Recommended separation distances between
portable and mobile RF communications equipment and the BM1001
The BM1001 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the BM1001 can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the BM1001 as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
