Electromagnetic Environment:
guidance
Portable and mobile RF
communications equipment
should be used no closer to any
part of the DigiTrak XT,
including cables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
D = 1.2vP
D = 1.2vP 80 MHz to 800 MHz
D = 2.3vP 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 metres (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked
