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 metres(m).
b
Field strengths form fixed RF
transmitters, as determined by an
electromagnetic site survey,
a
should
be less than the compliance level in
each frequency range.
b
Interference may occur in the vicinity
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 is affected by
absorption and reflection from structures, objects and people.
a
Field strengths from 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 filed strength in the location in which the
Pain Therapy Device is used exceeds the applicable RF compliance level above. The
Pain Therapy Device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or
relocating the Pain Therapy Device.
b
Over the frequency range 150kHz to 80 MHz, filed strengths should be less than
3V/m.
