Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
Crossre™ System is intended for use in the electromagnetic environment specied below. The
customer or the user of Crossre™ System should ensure that it is used in such an environment.

Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of
the Crossre™ system, including
its cables, than the recommended
separation distance calculated
from the equation applicable to the
frequency of the transmitter.
Recommended Separation Distance
d = 1.17 √P
Conducted RF

3 Vrms
150 kHz to 80

Radiated RF

3 V/m
80MHz to 2.5 GHz
3 V/m d = 2.33 √P
80 MHz to 2.5 GHz
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 xed 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:
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 reection from structures, objects, and people.
(a) Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If the measured
eld strength in the location in which the Crossre™ System is used exceeds the applicable RF
compliance level above, the Crossre™ System should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Crossre™ System.
(b) Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
