Portable and mobile RF
communications equipment
should be used no closer to
any part of PPoowweerr--PPRROO or
SSMMRRTT charger, including
cables, than the
recommended separation
distance calculated from the
equation appropriate for the
frequency of the transmitter.
Recommended separation
distance
D=(1.2) (√
P
)
D=(.18) (√
P
)
80 MHz to 800 MHz
D=(0.35) (√
P
)
800 MHz to 2.5 GHz
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
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:
Conducted RF
IEC 61000-4-6
3 Vrms
150kHz to 80MHz
3 V
Radiated RF
IEC 61000-4-3
20 V/m
80 MHz to 2.5 GHz
20 V/m
NNoottee 11:: At 80 MHz and 800 MHz, the higher frequency range applies.
NNoottee 22:: 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 PPoowweerr--PPRROO is used exceeds the applicable RF
compliance level above, the PPoowweerr--PPRROO system should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating PPoowweerr--PPRROO.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 20 V/m.
