NOTE 1 At 80 MHz and 800 MHz, 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
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 [DY310] is used
exceeds the applicable RF compliance level above, the
[DY310] should be observed to verify normal operation. If
abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the
[DY310].
b
Over the frequency range 150 kHz to 80 MHz, field
strengths should be less than 3 V/m.
