separation distance in
meters (m).
Field strengths from
fixed RF transmitters,
as determined by an
electromagnetic site
surveya, should be less
than the compliance
level in each frequency
rangeb.
Interference may
occur in the vicinity
of equipment marked
with the following
symbol:
м
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 PowerDot PD-01 device
is used exceeds the applicable RF compliance level above, the PowerDot
PD-01 device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
reorienting or relocating the PowerDot PD-01 device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.
