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
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 reflection from structures, objects, and people.
e.
The separation distances are calculated using the following equation adopted from the 4th edition draft of
iEC 60601-1-2:
d
= (5/
E
) √
P
where
P
is the maximum
output power of the transmitter in watts (W) according
to the transmitter
manufacturer
,
d
is the separation
distance in meters (m), and
E
is the
compliance level.
