Electromagnetic immunity environment tested
Portable and mobile RF communications equipment should be used no closer to any part of the CAMT, including cables, than the
recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people. 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 CAMT is used
exceeds the applicable RF compliance
level, the CAMT should be observed
to verify normal operation. If abnormal
performance is observed, additional
measures may be necessary, such as
reorienting or relocating the CAMT.
