NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the device, Including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
Considering to reduce the minimum
separation distance, based on RISK
MANAGEMENT,
and
using higher IMMUNITY
TEST LEVELS that are appropriate for the
reduced minimum separation distance.
Minimum separation distances for higher
IMMUNITY TEST LEVELS shall be calculated
using the following equation:
E
=
6/dff
where P is the maximum power in
w,
d ,s the
minimum separation distance in m, and E is
the IMMUNITY TEST LEVELS in V/m.
Field strengths from fixed AF transmitters,
as
determined by an electromagnetic site survey, 8
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:
(t'i'))
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 trans-milters, such as base stations for radio (cellular/cordless) tele-phones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast can-not be predicted theoretically with accuracy.
To assess the electro-magnetic environment due to fixed RF transmitters, an electromagnet-ic site survey should
be considered. If the measured field strength in the location In which the device is used exceeds the ap-plicable RF
compliance level above, the device should be ob-served to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the device.
b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
