For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration – electromagnetic immunity
The BF 408 is intended for use in the electromagnetic environment specified below. The customer or the
user of the BF 408 should assure that it is used in such an environment.
IMMUNITY test IEC 60601 test level Compliance level Electromagnetic environment – guidance
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 absorp-
tion 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 the-
oretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an elec-
tromagnetic site survey should be considered. If the measured field strength in the location in which the
BF 408 is used exceeds the applicable RF compliance level above, the BF 408 should be observed to ver-
ify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the BF 408.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
Portable and mobile RF communications equip-
ment should be used no closer to any part of
the BF 408, including cables, than the recom-
mended separation distance calculated from
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 and d is the recom-
mended 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 equip-
ment marked with the following symbol:
