, including
cables, than the recommended separation

transmitter.

Field strengths from fixed RF transmitters,

(a)
, should be less than the
compliance level in each frequency range
(b)
.Interferency may occur in the vicinity
of equipment marked with the follwing
symbol:
NOTE 1: At 80MHz and 800MHz, 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 mo
-
bile radios, amateur radio, AM and FM radio broadcast and TV broadcast, cannot be predicted theoretically with accu-
racy. 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 AMM240ED is used exceeds the applicable
RF compliance level above, the AMM240ED should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the AMM240ED.
(b) Over the frequency range 150kHz to 80MHz, field strengths should be less than [V1] V/m.
