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

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