a.
The LA
TITUDE Communicator is
intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The
customer or the user of the LA
TITUDE
Communicator can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the LA
TITUDE
Communicator as recommended in Table 4, according to the maximum output power of the communications equipment.
b.
For transmitters rated at a maximum output power not listed above, the recommended separation distance
d
in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter
, where
P
is the
maximum output power rating of the transmitter in W
atts (W) according to
the transmitter manufacturer
.
c.
At 80 MHz, 800 MHz, and 1 GHz, the separation distance for the highest frequency range applies.
d.
These guidelines may not apply in all situations. Electromagnetic propagation is af
fected by absorption and re
fl
ection
from structures, objects, and people.
