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,
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
Propex IQ
®
Apex Locator is used exceeds the applicable
RF compliance level above, the
Propex IQ
®
Apex Locator should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the
Propex IQ
®
Apex Locator.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
