Portable and mobile RF communications equipment
should be used no closer to any part of the models
Rooter

X3000, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d=1.2×P1/2
d=2×P1/2
d=1.2×P1/2 80 MHz to 800 MHz
d=2.3×P1/2 800 MHz to 2.7 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:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
