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.

Electromagnetic environment -
guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the CGM MCB-1201 , including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
Recommended separation
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:
