Portable and mobile RF
communications equipment should
be used no closer to any part of
the NE-C801 including cables,
than the recommended separation
distance calculated from the equation
appropriate to the frequency of the
transmitter.
Recommend separation distance
d=1.2√P
d=1.2√P 80 MHz to 800 MHz
d=2.3√P 800 MHz to 2.5 GHz
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 determined by an
electromagnetic site survey,*

should
be less than the compliance level in
each frequency range.*

Interference may occur in the
vicinity of equipment marked with he
following symbol:
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.

Fieldstrengthsfromfixedtransmitters,suchasbasestationsforradio(cellular/cordless)
telephonesandlandmobileradio,AMandFMradiobroadcast,andTVbroadcastcannotbe
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 NE-C801 is used exceeds the applicable RF compliance
level above, the NE-C801 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or
relocating the NE-C801.
