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 ×
d = 1.2 × 80 MHz to 800 MHz
d = 2.3 × 800 MHz to 2.7GHz
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

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 people.
a 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 system is used
exceeds the applicable RF compliance level above, system should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the system.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
