the transmitter manufacturer and d is the
recommended separation distance in metres (m).
Field strength from 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 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 Urgent
PC Stimulator is used exceeds the applicable RF compliance level above, the Urgent PC
Stimulator should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the
Urgent PC Stimulator
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
