Portable and mobile RF communications equipment
should be used no closer to any part or the V1410 /
V1412, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:
Where:
P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer
and d is the recommended separation distance in
meters (m).
Field strengths from fixed RF transmitters, as deter-
mined by an electromagnetic site survey
a
, should be
less than the compliance level in each frequency
range
b
.
Interference may occur in the vicinity of equipment
marked with the following symbol:
NOTE 1. At 80MHz 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
V1410 / V1412 is used exceeds the applicable RF compliance level above, the V1410 / V1412 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the V1410 / V1412.
b Over the frequency range 150kHz to 80 MHz, field strengths should be less than [V1] V/m.
