EMC data
Guidance and manufacturer's declaration - electromagnetic immunity - for
equipment and system that are not life-supporting. The model BW-SC2 is intended
for use in the electromagnetic environment specified below. The customer or the user
of the model BW-SC2 should assure that it is used in such an environment.

Field strengths from fixed RF transmitters, as determined by an
GHz
electromagnetic site survey, should be less than the compliance
level in each frequency range. b Interference may occur in the vi-
cinity 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 consid-
ered. If the measured field strength in the location in which the BW-SC2 is used exceeds the
applicable RF compliance level above, the Medical BW-SC2 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be nec-
essary, such as reorienting or relocating the BW-SC2.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1]
V/m.
