Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: 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/
a
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 fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the
EasyOne Pro/LAB is used exceeds the applicable RF compliance level above, the
EasyOne Pro/LAB should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or
relocating the EasyOne Pro/LAB.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidance
Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or
hospital environment.
Portable and mobile RF communications
equipment should be used no closer to
any part of the EasyOne Pro/LAB,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance:
d 0.35 P 150 kHz to 80 MHz
=
d 0.35 P 80 MHz to 800 MHz
=
d 0.7 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,
less than the compliance level in each
b
frequency range.
