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

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

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 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 150kHz to 80MHz, field strengths should be less than
3V/m.
