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.

Portable and mobile RF
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:
Radiated RF
IEC 61000-4-3
3 V/m
80MHz -
2.5GHz
3 V/m
Note 1 At 80 MHz and 800 MHz, 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 human body.
