Guidance and manufacturer's declaration – electromagnetic immunity
The model LND018915V3 is intended for use in the electromagnetic environment specified
below. The customer or the user of the model LND018915V3 should ensure that it is used in
such an environment.

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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
a
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 fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the model LND018915V3
is used exceeds the applicable RF compliance level above, the model LND018915V3
should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the model
LND018915V3.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

Electromagnetic environment –
guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the model LND018915V3, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d=1.167√P
d=1.167√P 80MHz to 800MHz
d=2.333 √P 800MHz 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 metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
a
survey, should be less than the compliance
level in each frequency range.
