Portable and mobile RF
communications equipment should
be used no closer to any part of this
device, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distances
d
＝
1.2 √P 150 kHz to 80 MHz
d
＝
1.2 √P 80 MHz to 800 MHz
d
＝
2.3 √P 800 MHz to 2.7 GHz
Where P is the maximum output
power rating of the transmitter in
watts (W) according to the
transmitter manufacturer, E is the
compliance level in V/m and d is the
recommended separation distance in
meters (m).
Field strengths from fixed RF
transmitters, as determined 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 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 ratio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicated
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
this device is used exceeds the applicable RF compliance level above, this device should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting of relocating this device.
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
(c)
The ISM (Industrial, Scientific and Medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz to
6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
