GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
THE BW-SC2W AND BW-SC6W ARE INTENDED FOR USE IN THE ELECTROMAGNETIC ENVIRONMENT SPECI-
FIED BELOW. THE CUSTOMER OR THE USER OF THE BW-SC2W AND THE BW-SC6W SHOULD ENSURE THAT
THEY ARE USED IN SUCH AN ENVIRONMENT.

that the BW-SC2W and the BW-SC6W
be powered from an uninterruptible
power supply or a battery.

Portable and mobile RF communications equipment should

including cables, than the recommended separation distance

Where P is the maximum output power rating of the transmitter in

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. b Interference may occur in the vi-

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 BW-SC2W and BW-SC6W is used exceeds the applicable RF compliance
level above, the BW-SC2W and BW-SC6W should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating
the BW-SC2W and BW-SC6W.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1]V/m.
