Portable and mobile RF
communications equipment should
be used no closer to any part of the
LEDEX
TM
WL-090, including cables,
than the recommended separation
distance calculated from the
equation applicable to the frequency
of the transmitter.
Recommend 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 he
transmitter manufacturer and d is the
recommended separation distance in
meters (m).
FieldstrengthsfromxedRF
transmitters as determined by an
electromagnetic site surveyª, should
be less than the compliance level in
each frequency range

.
Interference may occur in the vicinity
of equipment marked with the
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reectionfromstructures,objects,andpeople.
1. 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xedRFtransmitters,anelectromagneticsite
surveyshouldbeconsidered.Ifthemeasuredeldstrengthinthelocationinwhich
the LEDEX
TM
WL-090 is used exceeds the applicable RF compliance level above,
the LEDEX
TM
WL-090 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting
or relocating the LEDEX
TM
WL-090.
2. Overthefrequencyrange150kHzto80MHz,eldstrengthsshouldbelessthan3V/m.
