GUIDANCE AND MINDRAY DECLARATION—ELECTROMAGNETIC IMMUNITY
This system is intended for use in the electromagnetic environment specified below. The
customer or the user of this 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 this system, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d = 3.5 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).b
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a should be less than the compliance level in
each frequency range b
Interference may occur in the vicinity of
equipment marked with the following symbol:
Radiated RF
IEC 61000-4-3 3 V/m 80MHz to
2.5 GHz
3V/m
Note:
1. At 80 MHz and 800 MHz, the higher frequency range applies.
2. These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
z
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which this system
is used exceeds the applicable RF compliance level above, this system should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating this system.
z
Over the frequency ranges 150kHz to 80MHz, field strengths should be less than 1V/m.
