Note 1) Ut is the A.C. mains voltage prior to application of the 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 [V 1] V/m.
Electromagnetic
environment - guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the CGM MB-1901, including
cables, than the recommended eparation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
Recommended separation distance distance
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:
