Recommended separation distances between portable and mobile RF
communications equipment and the
model extriCARE™ 2400
.
The
model extriCARE™ 2400
is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of
the
model extriCARE™ 2400
can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the
model extriCARE™ 2400
as
recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d in metres (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 watts (W) according to the transmitter
manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
