Note 2
: These guidelines may not apply to 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 MA 27/ MA 27e is used exceeds the applicable RF compliance
level above, the MA 27/ MA 27e should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the MA 27/ MA 27e.
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
