Portable and mobile RF communications
equipment should be used no closer to any part
of the KNEESUP Smart Core
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 80MHz to 800 MHz
d = 2,3 800MHz 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).
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
