Portable and mobile RF communications
equipment should be used no closer to
any part of the Pro7HC, including cables, than
the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.

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).
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 Pro7HC is used exceeds
the applicable RF compliance level above, the Pro7HC should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Pro7HC.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
