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.
NOTE 3 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 meters (m). Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
range. Interference may occur in the vicinity of equipment marked with the following
b
symbol:
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 AccelStim device is used exceeds the applicable RF compliance level above,
the AccelStim device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting
or relocating the AccelStim device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
