Field strengths from fixed
RF transmitters, as
determined by an
electromagnetic site
a
survey, should be less
than the compliance level
b
in each frequency range.
Interference may occur In
the vicinity of equipment
marked with the following.
NOTE I At 80 MHz ends 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 du to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured
field strength in the location in which the SoundCare™ Plus device
is used exceeds the applicable RF compliance level above,
should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be
necessary, such as reorienting or relocating the SoundCare™ Plus.
b. Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than [V ] V/m.
