should be used no closer to any
part of the Wave Analyzer Medica
700, including clables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
where P is the maximum output
power rating of the transmitter in
watts (W) according to the
manufacturer and d is the
recommended separation
distance in meters (m).
Field strengths 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 solutions. Electromagnetic propagation is
affected by absorption and reflection form 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
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 Wave Analyzer
Medica 700 is used exceeds the applicable RF compliance level above, the Wave
Analyzer Medica 700 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or
relocating the Wave Analyzer Medica 700.
b
Over the frequency range 150 kHz à 80 MHz, field strengths should be less than 3 V/m.
