TABLE 3
GUIDANCE AND MINDRAY DECLARATION—ELECTROMAGNETIC IMMUNITY
The system is intended for use in the electromagnetic environment specified below. The customer
or the user of system should assure that it is used in such an environment.

communications equipment should
be used no closer to any part of
system, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter. Recommended
separation distance
d = 1.2 x
P
d = 1.2 x P 80 MHz to 800 MHz
d = 2.3 x
P 800 MHz to 2.5GHz
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, should
be less than the compliance level in
each frequency range.
Interference may occur in the vicinity
of equipment marked with the
following symbol:

Note 2These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
