Portable and mobile RF communications equipment should be used no closer to any part
of the PRO-33 / PRO-35, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d=1.2 P
d=1.2 P 80 MHz to 800 MHz
d=2.3 P 800 MHz to 2,5 GHz
where P is the maximum output power rating of the ransmitter in watts (W) according
to the transmitter manufacturer and d is the recommended separation distance in
metres (m).
Field strengths from fi xed RF transmitters, as determined by an electromagnetic site
survey

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 refl ection from
structures, objects and people.
a. Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be considered. If the measured
fi eld strength in the location in which the PRO-33 / PRO-35 is used exceeds the applicable RF compliance level above, the PRO-
33 / PRO-35 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the PRO-33 / PRO-35.
b. Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
