Guidance and Manufacturer's Declaration: Electromagnetic Immunity
X8000 is intended for use in the electromagnetic environment specified below. The customer or
the user of X8000 should ensure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the X8000 system, including
its cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended Separation Distance
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 the X8000 system is used exceeds the applicable RF compliance level
above, the X8000 system should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the X8000 unit.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
