Portable and mobile RF commu-
nications equipment should be
used no closer to any part of the
device, including cables, than the
recommended separation distance
calculated from the equation ap-
plicable to the frequency of the
transmitter.
Recommended separation
distance:
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 2.5 GHz
where P is the maximum output
power rating of the transmitter in
watts (W) according to the trans-
mitter manufacturer and d is the
recommended separation distance
in meters (m).

IMPORTANT: At 80 MHz and 800 MHz, the higher
frequency range applies.
IMPORTANT: These guidelines may not apply in all
situations. Electromagnetic propagation is a ect-
ed by absorption and refl ection from structures,
objects, and people.

Field strengths from fi xed transmitters, such
as base stations for radio (cellular/cordless) tel-
ephones 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 fi xed RF transmitters, an electromagnetic site
survey should be considered. If the measured fi eld
strength in the location in which the Zen-Olite™ is
used exceeds the applicable RF compliance level
above, the concentrator should be observed to
verify normal operation. If abnormal performance is
observed, additional measures may be necessary,
such as reorienting or relocating the concentrator.
b
Over the frequency range 150 kHz to 80 MHz,
fi eld strengths should be less than 6 V/m.
