Compliance Electromagnetic environment – guidance
level
6 kV contact Floors should be wood, concrete or ceramic tile. If floors are covered with synthetic material,
8 kV air the relative humidity should be at least 30 %.
Mains power quality should be that of a typical commercial or hospital environment.
Not applicable
Mains power quality should be that of a typical commercial or hospital environment.
Not applicable
Portable and mobile RF communications equipment should be used no closer to any part of
the FT55 series, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
d = 1.2 80 MHz to 800 MHz
Not applicable
d = 2.3 800 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
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:
