Portable and mobile RF communications equipment
should be used no closer to any part of the disposal
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
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 deter-
mined 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:
Notes:
(1) At 80 MHz and 800 MHz, the higher frequency range applies.
(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 PIEZO SMART is used exceeds the applicable RF compliance level above, the PIEZO SMART should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the PIEZO SMART.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
