Caution
1. At 80 MHz and 900 MHz, the higher frequency range applies.
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 EX PLUS 1300 is used
exceeds the applicable RF compliance level above, the EX PLUS 1300
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or
relocating the EX PLUS 1300.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
