NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 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 MCC-3000MT is used exceeds the
applicable RF compliance level above, the MCC-3000MT should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the MCC-3000MT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
MCC-3000MT
part of the
than the recommended separation distance
calculated from the equation appliance 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 meters
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
a
survey, should be less than the compliance
level in each frequency range.
Interference may occur in the vicinity of
equipment marked with following symbol:
