9.2 Electromagnetic immunity
Note:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note:
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.

Not applicable Portable and mobile RF communications
equipment should be used no closer to any part of
the THixyz series, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

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
