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 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:
Note 1) Uт is the A.C. mains voltage prior to application of the test level.
Note 2) At 80 MHz and 800 MHz, the higher frequency range applies.
Note 3) 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
EUT is used exceeds the applicable RF compliance level above, the EUT should be observed to
verifynormal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the EUT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V / m.
Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the FireCR Spark system.
The FireCR Spark system is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The user of the FireCR Spark system can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the FireCR Spark system as recommended
below, according to the maximum output power of the communications equipment.
